The Math.min()
function returns the smallest of zero or more numbers.
Math.min([value1[, value2[, ...]]])
value1, value2, ...
Because min()
is a static method of Math
, you always use it as Math.min()
, rather than as a method of a Math
object you created (Math
is not a constructor).
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.
Math.min()
This finds the min of x
and y
and assigns it to z
:
var x = 10, y = -20; var z = Math.min(x, y);
Math.min()
Math.min()
is often used to clip a value so that it is always less than or equal to a boundary. For instance, this
var x = f(foo); if (x > boundary) { x = boundary; }
may be written as this
var x = Math.min(f(foo), boundary);
Math.max() can be used in a similar way to clip a value at the other end.
