Math
The Math object holds a set of constants and methods that enable more complex mathematical operations than the basic arithmetic operators. We can not instantiate a Math Object. The Math object is static so it‟s properties and methods are accessed directly.
Ex:-
Math.PI
Math.abs( )
Properties
- E Returns Euler’s number (approx. 2.718)
- LN2 Returns the natural logarithm of 2 (approx. 0.693)
- LN10 Returns the natural logarithm of 10 (approx. 2.302)
- LOG2E Returns the base-2 logarithm of E (approx. 1.442)
- LOG10E Returns the base-10 logarithm of E (approx. 0.434)
- PI Returns PI (approx. 3.14)
- SQRT1_2 Returns the square root of 1/2 (approx. 0.707)
- SQRT2 Returns the square root of 2 (approx. 1.414)
Methods
- Math.abs(arg) Returns the absolute value of arg

- Math.acosh(arg) Returns the hyperbolic arccosine of arg
- Math.asin(arg) Returns the arcsine of arg, in radians
- Math.asinh(arg) Returns the hyperbolic arcsine of arg
- Math.atan(arg) Returns the arctangent of arg as a numeric value between -PI/2 and PI/2 radians
- Math.atan2(arg1, arg2) Returns the arctangent of the quotient of its arguments

- Math.min(arg1, arg2, …,arg_n) Returns the number with the lowest value
- Math.pow(arg1, arg2) Returns the value of arg to the power of arg2
- Math.sin(arg) Returns the sine of arg (arg is in radians)
- Math.sinh(arg) Returns the hyperbolic sine of arg
- Math.sqrt(arg) Returns the square root of arg
- Math.tan(arg) Returns the tangent of an angle
- Math.tanh(arg) Returns the hyperbolic tangent of a number
