Javascript Math Floor Decimal Places

A couple of improvements i can think of.

Javascript math floor decimal places.

The floor method rounds a number downwards to the nearest integer and returns the result. We were able to round the float 2 333 to 2 decimal places. This is a solid answer. Math floor value 100 100 tofixed 2.

It truncates cuts off the dot and the digits to the right of it no matter whether the argument is a positive or negative number. 1 vs code typescript file doesn t like math round passing in a string. The output type of tofixed is a string which needs to be passed to a top level function called parsefloat to return a number unfortunately this seems to be really slow. Unlike the other three math methods.

This rounded the number to 4 decimal places resulting in 383 4891. If the passed argument is an integer the value will not be rounded. As you probably know weird precision things can happen with floating point values and on the other side of the spectrum if the number happens to be 15 sounds like the op wants 15 00. A number can be rounded off to upto 2 decimal places using two different approaches in javascript.

I d still output the result of the above using tofixed though so. The tofixed method converts a number into a string rounding to a specified number of decimals. If the desired number of decimals are higher than the actual number zeros are added to create the desired decimal length. 1 that should solve the rounding issue.

Math floor x parameters x a number. The string 9 01345 was rounded to 9 01. Math floor math ceil and math round the way math trunc works is very simple. An integer such as 5 will become 5 00 with two zeros being appended behind the decimal place.

A number representing the largest integer less than or equal to the specified number. The number tofixed method takes an integer as an input and returns the the given number as a string in which the fraction is padded to the input integers length. For 383 48910093 we changed the second parameter to 4. 2 make number of decimal places dynamic not hard coded to 2.
