JavaScript Math. floor (rounded down to the value), math. floor rounded down

JavaScript Math. floor Method
The Math. floor method is used to round down a value to obtain the maximum integer that is less than or equal to the value. Syntax:

Math. floor (x)
Parameter description:

Parameters	Description
X	Required. It must be a numerical value.

Math. floor method example

<Script language = "JavaScript"> document. write (Math. floor (0.35) + "<br/>"); document. write (Math. floor (10) + "<br/>"); document. write (Math. floor (-10) + "<br/>"); document. write (Math. floor (-10.1); </script>

Run this example and output:

0
10
-10
-11

Math. floor may be inaccurate.

If the parameter x is an expression involving a floating point number, the inherent principle of the computer may cause the expression to apply Math. the result after the floor method is inaccurate (not in line with common sense). For details, refer to Math. description in ceil method.
