Predefined Objects

Let us assume some of the most frequently utilized predefined objects provided in Javascript.

Math object

In most of the applications we have to perform calculations, whether this is accounting software or scientific software. Programmers are frequently typecast as good mathematicians. Every mathematician required a calculator sometimes, or in the particular case of JavaScript, the Math object. If we desire to calculate "2.5 to the power of 8" or "Sin0.9" in your script, then JavaScript's virtual calculator is what you desire. The Math object have a number of manipulating functions:

The Math object

Methods

Description

Math.abs(x)

Return absolute value of x

Math.acos(x)

Return arc cosine of x in radians

Math.asin(x)

Return arc sine of x in radians

Math.atan(x)

Return arc tan of x in radians

Math.atan2(x, y)

Counterclockwise angle among x axis & point (x,y)

Math.ceil(x)

Rounds a number up

Math.cos(x)

Trigonometric cosine of x (x in radians)

Math.exp(x)

Exponential method ex

Math.floor(x)

Rounds number down

Math.log(x)

Natural logarithm of x (base e)

Math.max(a, b)

Returns the larger of two values

Math.min(a, b)

Returns the smaller of two values

Math.pow(x, y)

Returns xy

Math.round(x)

Rounds x to the closest integer

Math.sin(x)

Trigonometric sine of x (x in radians)

Math.sqrt(x)

Square root of x

Math.tan(x)

Trigonometric tangent of x (x in radians)

Properties

Description

Math.E

Euler's constant ( ~ 2.718)

Math.LN10

Natural logarithm of 10 (~ 2.302)

Math.LN2

Natural logarithm of 2 (~ 0.693)

Math.LOG10E

Base 10 logarithm of Euler's constant (~          0.0434)

Math.LOG2E

Base 2 logarithm of Euler's constant (~1.442)

Math.PI

The ratio of a circle's circumference to its   diameter

(~3.141)

Math.SQRT1_2

Square root of 0.5 ( ~ 0.707)

Math.SQRT2

Square root of 2.0 ( ~ 1.414)

 

Let us encompass Javascript perform some mathematical calculations: 

  //calculate e                                                                                                                                    

Math.exp(5)                                                                                                                                       

//calculate cos(2PI)

Math.cos(2*Math.PI)                                                                                                                        

The "with" statement

If you intend to invoke Math multiple times in your script, a good statement to remember is "with." Using it you can omit the "Math." prefix for any subsequent Math properties/methods:

with (Math){ var x= sin(3.5) var y=tan(5)

var result=max(x,y)

}
