Summary
The Math.max() function returns the largest of zero or more numbers.
Syntax
Math.max([value1[,value2, ...]]) Parameters
-
value1, value2, ... - Numbers.
Description
Because max is a static method of Math, you always use it as Math.max(), rather than as a method of a Math object you created.
If no arguments are given, the result is - Infinity.
If at least one of arguments cannot be converted to a number, the result is NaN.
Examples
Example: Using Math.max
Math.max(10, 20) returns 20.
Math.max(-10, -20) returns -10.
Math.max(-10, 20) returns 20.
function getMaxOfArray(numArray) {
return Math.max.apply(null, numArray);
}
This function uses apply to find the maximum element in a numeric array. getMaxOfArray([1,2,3]) is equivalent to Math.max(1, 2, 3), but you can use getMaxOfArray on programmatically constructed arrays of any size.
