How can I remove the decimal part from JavaScript number?
You could use...
Math.trunc()
(truncate fractional part, also see below)Math.floor()
(round down)Math.ceil()
(round up)Math.round()
(round to nearest integer)
...dependent on how you wanted to remove the decimal.
Math.trunc()
isn't supported on all platforms yet (namely IE), but you could easily use a polyfill in the meantime.
Another method of truncating the fractional portion with excellent platform support is by using a bitwise operator (.e.g |0
). The side-effect of using a bitwise operator on a number is it will treat its operand as a signed 32bit integer, therefore removing the fractional component. Keep in mind this will also mangle numbers larger than 32 bits.
You may also be talking about the inaccuracy of decimal rounding with floating point arithmetic.

If you don't want any numbers after the decimal, with Javascript you can use Math.trunc(3.75)
"The Math.trunc() function returns the integer part of a number by removing any fractional digits."

Remove numbers after decimal in javascript
If you need to set the amount of decimal places in a number, you can use toFixed(X)
, where X is the amount of decimal places you want to have.
For example,
4.589729345235789.toFixed(1);
would result in 4.6
.
Keep in mind, this will convert the number into a string.
If you need absolute accuracy and 4.6
is not good enough for you, see this Stackoverflow post, which has this as a more "accurate" method for your case:
var with2Decimals = num.toString().match(/^-?\d+(?:\.\d{0,2})?/)[0]
Notice the {0,2}
inside of that, which is the range. You can change it to {0,1}
in your case.
