JavaScript Math Object

// Math.abs(x) returns the absolute (positive) value of x
Math.abs(-3.14);   // Returns 3.14
 
// Math.ceil(x) returns the value of x rounded up to its nearest integer
Math.ceil(3.14);  // Returns 4
 
// Math.cos(x) returns the cosine (a value between -1 and 1) of the angle x (given in radians).
// Convert degrees to radians if you want to use degrees instead of radians, like this:
// Angle in radians = Angle in degrees x PI / 180.
Math.cos(0 * Math.PI / 180);  // Returns 1 (the cos of 0 degrees)
 
// Math.floor(x) returns the value of x rounded down to its nearest integer
Math.floor(3.14);  // Returns 3
 
// Math.max() is used to find the highest value in a list of arguments
Math.max([x[, y[, �]]])
Math.min(920, 70, 30, 0, -15, -5);  // Returns 920
 
// Math.min() is used to find the lowest value in a list of arguments
Math.min(920, 70, 30, 0, -15, -5);  // Returns -15
 
// Math.pow(x, y) returns the value of x to the power of y
Math.pow(5, 2)  // Returns 25
 
// Math.random() returns a random number between 0 (inclusive),  and 1 (exclusive):
Math.random();  // Returns a random number
 
// Math.round(x) returns the value of x rounded to its nearest integer
Math.round(3.14);  // Returns 3
Math.round(3.7);   // Returns 4
 
// Math.sin(x) returns the sine (a value between -1 and 1) of the angle x (given in radians).
// Convert degrees to radians if you want to use degrees instead of radians, like this:
// Angle in radians = Angle in degrees x PI / 180.
Math.sin(90 * Math.PI / 180);  // Returns 1 (the sine of 90 degrees)
 
// Math.sqrt(x) returns the square root of x
Math.sqrt(25);  // Returns 5
