JavaScript Math Object
JavaScript - Math.PI
Math.PI return the value of PI
JavaScript - Math.round()
Math.round(x) returns the value of x rounded to its nearest integer.
JavaScript - Math.pow()
Math.pow(x, y) returns the value of x to the power of y:
JavaScript - Math.sqrt()
Math.sqrt(x) returns the square root of x.
JavaScript - Math.abs()
Math.abs(x) returns the absolute (positive) value of x.
JavaScript - Math.ceil()
Math.ceil(x) returns the value of x rounded up to its nearest integer.
JavaScript - Math.floor()
Math.floor(x) returns the value of x rounded down to its nearest integer.
JavaScript - Math.sin()
Math.sin(x) returns the sine (a value between -1 and 1) of the angle x (given in radians).
If you want to use degrees instead of radians, you have to convert degrees to radians:
Angle in radians = Angle in degrees x PI / 180.
JavaScript - Math.cos()
Math.cos(x) returns the cosine (a value between -1 and 1) of the angle x (given in radians).
If you want to use degrees instead of radians, you have to convert degrees to radians:
Angle in radians = Angle in degrees x PI / 180.
Math.min() and Math.max()
Math.min() and Math.max() can be used to find the lowest or highest value in a list of arguments.
Example
Math.min(0, 150, 30, 20, -8, -200); // returns -200
Math.max(0, 150, 30, 20, -8, -200); // returns 150
JavaScript - Math.random()
Math.random() returns a random number between 0 (inclusive), and 1 (exclusive).
