The method of obtaining the absolute value of variable in JS _javascript skill

This paper illustrates the method of obtaining the absolute value of variables in JS. Share to everyone for your reference. The specific analysis is as follows:

Absolute value in JS we directly use the ABS function to seek, here to sort out some of the absolute value of the variable in JS, so that we have a deeper understanding of the use of JS absolute value

JS in the absolute value is not commonly used to, today in the writing of a method encountered, and then recorded, and we learn together.

The default object--math object in JS has an ABS function, which is designed to get the absolute value of the number, such as:

Copy Code code as follows:

Math.Abs (-1); 1
Math.Abs (-2); 2

Of course, this function can also be used to get the absolute value of a variable, such as:

Copy Code code as follows:

var aaa=-3;
var bbb=abs (AAA); 3

Example:

Copy Code code as follows:

<script language= "JavaScript" >
document.write ("0 of the absolute value is:", Math.Abs (0), "<br>");
document.write ("1 of the absolute value is:", Math.Abs (1), "<br>");
document.write ("1 of the Absolute value:", Math.Abs ( -1), "<br>");
-->
</script>

Another method:
We know that the absolute value in mathematics is either Decimal or integer, and this is certainly the case.

Copy Code code as follows:

var aaa=-3.3;
var bbb=abs (AAA); 3.3

I hope this article will help you with your JavaScript programming.
