JavaScript supports the following mathematical
functions (methods of the Math
object):
Math.abs(a) // the absolute value of a Math.acos(a) // arc cosine of a Math.asin(a) // arc sine of a Math.atan(a) // arc tangent of a Math.atan2(a,b) // arc tangent of a/b Math.ceil(a) // integer closest to a & not less than a Math.cos(a) // cosine of a Math.exp(a) // exponential of a Math.floor(a) // integer closest to & not greater than a Math.log(a) // log of a base e Math.max(a,b) // the maximum of a and b Math.min(a,b) // the minimum of a and b Math.pow(a,b) // a to the power b Math.random() // pseudorandom number in the range 0 to 1 Math.round(a) // integer closest to a Math.sin(a) // sine of a Math.sqrt(a) // square root of a Math.tan(a) // tangent of a Math.PI // π(if you use "with(Math) {...}" do not use "Math."
