Html input types float

Is there a float input type in HTML5?

Yet it is simply (in the latest version of Chrome, anyway), an «updown» control with integers, not floats:

input type="number" id="totalAmt">input> 

Is there a floating point input element native to HTML5, or a way to make the number input type work with floats, not ints? Or must I resort to a jQuery UI plugin?

Solution 1 — Html

The number type has a step value controlling which numbers are valid (along with max and min ), which defaults to 1 . This value is also used by implementations for the stepper buttons (i.e. pressing up increases by step ).

Simply change this value to whatever is appropriate. For money, two decimal places are probably expected:

(I’d also set min=0 if it can only be positive)

If you’d prefer to allow any number of decimal places, you can use step=»any» (though for currencies, I’d recommend sticking to 0.01 ). In Chrome & Firefox, the stepper buttons will increment / decrement by 1 when using any . (thanks to Michal Stefanow’s answer for pointing out any , and see the relevant spec here)

Here’s a playground showing how various steps affect various input types:

form> input type=number step=1 /> Step 1 (default)br /> input type=number step=0.01 /> Step 0.01br /> input type=number step=any /> Step anybr /> input type=range step=20 /> Step 20br /> input type=datetime-local step=60 /> Step 60 (default)br /> input type=datetime-local step=1 /> Step 1br /> input type=datetime-local step=any /> Step anybr /> input type=datetime-local step=0.001 /> Step 0.001br /> input type=datetime-local step=3600 /> Step 3600 (1 hour)br /> input type=datetime-local step=86400 /> Step 86400 (1 day)br /> input type=datetime-local step=70 /> Step 70 (1 min, 10 sec)br /> form> 

As usual, I’ll add a quick note: remember that client-side validation is just a convenience to the user. You must also validate on the server-side!

Solution 2 — Html

> But what if you want all the numbers to be valid, integers and decimals alike? In this case, set step to “any”

Works for me in Chrome, not tested in other browsers.

Solution 3 — Html

input type="number" step="any" min="0" max="100" value="22.33"> 

Solution 4 — Html

You can use the step attribute to the input type number:

input type="number" id="totalAmt" step="0.1">input> 

step=»any» will allow any decimal.
step=»1″ will allow no decimal.
step=»0.5″ will allow 0.5; 1; 1.5; .
step=»0.1″ will allow 0.1; 0.2; 0.3; 0.4; .

Solution 5 — Html

type="text" >"sno" placeholder="Only float with dot !" onkeypress="return (event.charCode >= 48 && event.charCode > 

• 48-57 equal to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
• 0 is Backspace (otherwise need refresh page on Firefox)
• 46 is dot

if you try float with comma :

type="text" >"sno" placeholder="Only float with comma !" onkeypress="return (event.charCode >= 48 && event.charCode > 

Supported Chromium and Firefox (Linux X64)(other browsers I does not exist.)

Solution 6 — Html

 input id="relacionac" name="relacionac" type="number" min="0.4" max="0.7" placeholder="0,40-0,70" class="form-control input-md" step="0.01"> 

then, I define min in 0.4 and max in 0.7 with step 0.01: 0.4, 0.41, 0,42 . 0.7

I have started using inputmode=»decimal» which works flawlessly with smartphones:

Note that we have to use type=»text» instead of number . However, on desktop it still allows letters as values.

For desktop you could use:

which allows 0-9 and . as input and only numbers.

Note that some countries use , as decimal dividor which is activated as default on the NumPad. Thus entering a float number by Numpad would not work as the input field expects a . (in Chrome). That’s why you should use type=»text» if you have international users on your website.

You can try this on desktop (also with Numpad) and your phone:

Input with type text:
 input type="text" inputmode="decimal" value="1.5"> 
Input with type number:
 input type="number" inputmode="decimal" value="1.5">

yes this is the correct answer:

This is more efficient. Trust me.

document.getElementById('form1').addEventListener('submit', function(e)< e.preventDefault(); alert("Your nnumber is: "+document.getElementById('n1').value) alert("This works no ? :) please upvote") >) 

form id="form1"> input type="number" step="any" id="n1"> button type="submit">Submit button> form>

Solution 10 — Html

I just had the same problem, and I could fix it by just putting a comma and not a period/full stop in the number because of French localization.

2.5 is KO (The number is considered «illegal» and you receive empty value).

Solution 11 — Html

This worked for me and i think is the easiest way to make the input field accept any decimal number irrespective of how long the decimal part is. Step attribute actually shows the input field how many decimal points should be accepted. E.g, step=»0.01″ will accept only two decimal points.

Solution 12 — Html

Using React on my IPad, type=»number» does not work perfectly for me. For my floating point numbers in the range between 99.99999 — .00000 I use the regular expression (^1$)|(^5\.2$) . The first group (. ) is true for all positive two digit numbers without the floating point (e.g. 23), | or e.g. .12345 for the second group (. ) . You can adopt it for any positive floating point number by simply changing the range or respectively.

className="center-align" type="text" pattern="(^3$)|(^4\.1$)" step="any" maxlength="7" validate="true" /> 

Solution 13 — Html

This topic (e.g. step=»0.01″ ) relates to stepMismatch and is supported by all browsers as follows:

Solution 14 — Html

If any of the methods doesn’t work you can use parse float.

const totalAmt = document.getElementById("totalAmt"); totalAmt.addEventListener("change", (e)=>< // e.preventDefault(e); const result = parseFloat(e.target.value); console.log(result) >); 

input type="text" id="totalAmt" />

Which is the Float Input Type in HTML5

The “number” type field is intended to use for numerical values. It has some useful attributes such as min , max , and step . For a number field, a valid value should be a floating-point number between specified minimum and maximum values. If a step attribute is set, a valid value will be divisible by the step value.

The step attribute will control which values are valid. So, change this value to whatever you need. Some browsers will add toggle buttons to increment/decrement the values by the value specified with the step . If no value is specified, it will be set to 1 by default.

Example of using type=»number» with its min , max , and step attributes:

html> html> head> title>Title of the document title> head> body> form action="/form/submit" method="post"> input type="number" min="5" max="25" step="5"> form> body> html>

Here, the valid input would be 5, 10, 15, 20, and 25, and any other value will be rejected.

For any floating-point numbers, use type attribute»>step to allow any number of decimal places. Let’s see an example to understand how various steps affect different input types.

Example of using the step attribute with various input types:

html> html> head> title>Title of the document title> head> body> form action="/form/submit" method="post"> input type=number step=1 /> Step 1 (default) br /> input type=number step=0.01 /> Step 0.01 br /> input type=number step=any /> Step any br /> input type=range step=20 /> Step 20 br /> input type=datetime-local step=60 /> Step 60 (default) br /> input type=datetime-local step=1 /> Step 1 br /> input type=datetime-local step=any /> Step any br /> input type=datetime-local step=0.001 /> Step 0.001 br /> input type=datetime-local step=3600 /> Step 3600 (1 hour) br /> input type=datetime-local step=86400 /> Step 86400 (1 day) br /> input type=datetime-local step=70 /> Step 70 (1 min, 10 sec) br /> form> body> html>

HTML 5 input type=number element for floating point numbers on Chrome

It won’t have validation problems and the arrows will have step of «1»

Constraint validation: When the element has an allowed value step, and
the result of applying the algorithm to convert a string to a number
to the string given by the element’s value is a number, and that
number subtracted from the step base is not an integral multiple of
the allowed value step, the element is suffering from a step mismatch.

The following range control only accepts values in the range 0..1, and
allows 256 steps in that range:

The
following control allows any time in the day to be selected, with any
accuracy (e.g. thousandth-of-a-second accuracy or more):

Normally, time controls are
limited to an accuracy of one minute.

Allow 2 decimal places in input type=number

Instead of step=»any» , which allows for any number of decimal places, use step=».01″ , which allows up to two decimal places.

Html attribute ‘Max’ with float value make problems

You need to add the step property like this:

html5 input[type=number] two decimal points

No, you can’t do this with input[type=number] . Version numbers like 1.0.2 are not mathematically legal.

However, you can use input[type=text] and define a proper regular expression as its pattern attribute.

For example this one matches semantic versioning numbers:
