Advanced mathematical operations are provided through the Math object

The Math object is a built-in object containing properties and methods used for mathematical computation. It is a predefined JavaScript object and can be accessed without the use of a constructor or calling method. All Math properties and methods are static. Properties and Methods of the Math Object Property/MethodDescription abs()Returns absolute value of a number acos()Returns the arccosine of a number asin()Returns the arcsine of a number atan()Returns the arctangent of a number atan2()Returns the arctangent of the quotient of its parameters ceilReturns the smallest integer greater than or equal to a number cos()Returns the cosine of a number EReturns the value for Euler's constant exp()Returns Ex, where x is a number floor()Returns the largest integer less than or equal to a number LN10Returns the natural logarithm of 10 LN2Returns the natural logarithm of 2 log()Returns the natural logarithm (base E) of a number LOG10EReturns the base 10 logarithm of E LOG2EReturns the base 2 logarithm of E max()Returns the larger of two arguments min()Returns the smaller of two arguments PIReturns the value of PI pow()Returns base to the exponent power, baseexp random()Returns a random number between 0 and 1 round()Rounds a number to its nearest integer sin()Returns the sine of a number sqrt()Returns the square root of a number SQRT1_2Returns the square root of ? SQRT2Returns the square root of 2 tan()Returns the tangent of a number toSource()Creates a copy of an object toString()Returns a string representation of an object <html> <body> <title>Example of creating a Math object</title> <script language="JavaScript">  </script> </body> </html>
