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
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 e5
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)
}
