How do you get rid of decimals in html?
I have the results of a division and I wish to discard the decimal portion of the resultant number. How can I do this?

...dependent on how you wanted to remove the decimal.
Another method of truncating the fractional portion with excellent platform support is by using a
bitwise operator (.e.g You may also be talking about the inaccuracy of decimal rounding with floating point arithmetic. Required Reading - What Every Computer Scientist Should Know About Floating-Point Arithmetic. answered Oct 3, 2011 at 23:29
5 You can also use bitwise operators to truncate the decimal. e.g.
Bitwise operations are considerably more efficient than
the Math functions. The double not bitwise operator also seems to slightly outperform the
Also worth noting is that the bitwise not operator takes precedence over arithmetic operations, so you may need to surround calculations with parentheses to have the intended result:

Dave NewtonDave Newton 157k24 gold badges254 silver badges301 bronze badges With ES2015, Math.trunc() is available.
It's not supported in IE11 or below, but does work in Edge and every other modern browser. answered Apr 1, 2016 at 0:56
Chad von NauChad von Nau 4,2061 gold badge21 silver badges33 bronze badges 3 Here is the compressive in detailed explanation with the help of above posts: 1. Math.trunc() : It is used to remove those digits which are followed by dot. It converts implicitly. But, not supported in IE. Example: Math.trunc(10.5) // 10 Math.trunc(-10.5) // -10 Other Alternative way: Use of bitwise not operator: Example: x= 5.5 ~~x // 5 2. Math.floor() : It is used to give the minimum integer value posiible. It is supported in all browsers. Example: Math.floor(10.5) // 10 Math.floor( -10.5) // -11 3. Math.ceil() : It is used to give the highest integer value possible. It is supported in all browsers. Example: Math.ceil(10.5) // 11 Math.ceil(-10.5) // -10 4. Math.round() : It is rounded to the nearest integer. It is supported in all browsers. Example: Math.round(10.5) // 11 Math.round(-10.5)// -10 Math.round(10.49) // 10 Math.round(-10.51) // -11 answered Sep 22, 2017 at 7:31

1 If you don't care about rouding, just convert the number to a string, then remove everything after the period including the period. This works whether there is a decimal or not.

JaredJared 6211 gold badge7 silver badges18 bronze badges How do you remove a decimal value?Step 1: Write down the decimal divided by 1. Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.) Step 3: Simplify (or reduce) the Rational number.
How do you round off value in HTML?The Math.round() method rounds a number to the nearest integer. 2.49 will be rounded down (2), and 2.5 will be rounded up (3).
