JavaScript - Math.trunc() Method
The JavaScript Math.trunc() method is used to round the given number towards zero. It returns the nearest integral value with absolute value less than the argument.
Syntax
Math.trunc(x)
Parameters
x |
Specify a number. |
Return Value
Returns the nearest integral value with absolute value less than the argument.
Example:
In the example below, Math.trunc() method returns the nearest integral value with absolute value less than the argument.
var txt; txt = "Math.trunc(10.2) = " + Math.trunc(10.2) + "<br>"; txt = txt + "Math.trunc(10.5) = " + Math.trunc(10.5) + "<br>"; txt = txt + "Math.trunc(10.8) = " + Math.trunc(10.8) + "<br>"; txt = txt + "Math.trunc(-5.2) = " + Math.trunc(-5.2) + "<br>"; txt = txt + "Math.trunc(-5.5) = " + Math.trunc(-5.5) + "<br>"; txt = txt + "Math.trunc(-5.8) = " + Math.trunc(-5.8) + "<br>";
The output (value of txt) after running above script will be:
Math.trunc(10.2) = 10 Math.trunc(10.5) = 10 Math.trunc(10.8) = 10 Math.trunc(-5.2) = -5 Math.trunc(-5.5) = -5 Math.trunc(-5.8) = -5
