Syntax
Effect
Math.ceil(x)
Math.ceil(x) returns the smallest integer
value greater than or equal to x.
Math.floor(x)
Math.floor(x) returns the greatest integer
value less than or equal to x.
Math.round(x)
Math.round(x) returns the nearest integer
value to x.
Math.sqrt(x)
Returns the square root of x.
Math.sin(x)
Math.sin(x) returns the trigonometric
function sine of a radian argument.
Math.cos(x)
Math.cos(x) returns the trigonometric
function cosine of a radian argument.
Math.tan(x)
Math.tan(x) returns the trigonometric
function tangent of a radian argument.
Math.asin(x)
Math.asin(x) returns the arcsine of x in the
range -pi/2 to pi/2.
Math.acos(x)
Math.acos(x) returns the arc cosine of x in
the range 0 to pi.
Math.atan(x)
Math.atan(x) returns the arc tangent of x in
the range -pi/2 to pi/2.
Math.atan2(y,x)
Math.atan2(y, x) converts rectangular
coordinates (x, y) to polar coordinates (r,
a) by computing a as an arc tangent of y/x
in the range -pi to pi.
Math.exp(x)
Math.exp(x) computes the exponential
function.
Math.log(x)
Math.log(x) computes the natural logarithm
of x.
Math.pow(x,y)
