Math object
The Math object is a way of grouping together math-related constants and functions. In the descriptions below, the nearest integer below or above an integer is the integer itself, and the range [0, 1) includes 0 but not 1.
| Name | Meaning |
|---|---|
Math.PI |
the constant pi |
Math.floor(n) |
the nearest integer below |
Math.ceil(n) |
the nearest integer above |
Math.max(a, b, c) |
the maximum of the inputs |
Math.min(a, b, c) |
the minimum of the inputs |
Math.pow(a, b) |
a to the power b |
Math.sqrt(n) |
the square root of the input |
Math.random() |
a pseudorandom number in the range [0, 1) |
To obtain a pseudorandom integer in the range [0, x), for an integer x, you can use Math.floor(Math.random() * (x + 1)).
Click on the Run button several times to see the different pseudorandom numbers being generated. They will be in the range [0, 10).
