The Number.EPSILON property of the Number object represents the difference between 1 and the smallest floating point number greater than 1.SyntaxIts Syntax is as followsNumber.EPSILONExample Live Demo    JavaScript Example           var result = Number.EPSILON;       document.write("Value of the epsilon : " + result);     OutputValue of the epsilon: 2.220446049250313e-16

The tanh() function of the Math object accepts an angle (in radians) and returns its hyperbolic tangent value.SyntaxIts Syntax is as followsMath.tanh(90)Example Live Demo    JavaScript Example           var result = Math.tanh(90);       document.write("Hyperbolic tangent value of the given angle: "+result);     OutputHyperbolic tangent value of the given angle: 1

The sinh() function of the Math object accepts an angle (in radians) and returns its hyperbolic sine value.SyntaxIts Syntax is as followsMath.sinh(90)Example Live Demo    JavaScript Example           var result = Math.sinh(90);       document.write("Hyperbolic sine value of the given angle: "+result);     OutputHyperbolic sine value of the given angle: 6.102016471589204e+38

The cosh() function of the Math object accepts an angle (in radians) and returns its hyperbolic cosine value.SyntaxIts Syntax is as followsMath.cosh(90)Example Live Demo    JavaScript Example           var result = Math.cosh(90);       document.write("Hyperbolic cosine value of the given angle: "+result);     OutputHyperbolic cosine value of the given angle: 6.102016471589204e+38

The trunc() function of the Math object accepts a number and returns its integral point (excluding the fractional part). If the given number itself is an integer this function returns the same.SyntaxIts Syntax is as followsMath.trunc();Example Live Demo    JavaScript Example           var result = Math.trunc(58.745);       document.write("Integral part of the given number: "+result);     OutputIntegral part of the given number: 58

The sqrt() function of the Math object accepts a number and returns the square root value of the given number.SyntaxIts Syntax is as followsMath.sqrt();Example Live Demo    JavaScript Example           var result = Math.sqrt(169);       document.write("Square root value of the given number: "+result);     OutputSquare root value of the given number: 13

The sign() function of the Math object accepts an integer number and returns its sign.(positive, negative)If the given number is a positive integer then, this function returns +1.And, if the given number is a negative integer then, this function returns -1.SyntaxIts Syntax is as followsMath.sign();Example Live Demo    JavaScript Example           var result = Math.sign(-128);       document.write("Result: "+result);     OutputResult: -1

The round() function of the Math object accepts a floating point random number and returns its nearest integer value.If the given number is x.5 or more this function returns the next number (x+1)If the given number is x.4 or less this function returns the previous number (x-1).If the given number itself is an integer this function returns the same.SyntaxIts Syntax is as followsMath.round();Example Live Demo    JavaScript Example           var result = Math.round(2541.542);       document.write("Rounded value of the given number: "+result);     OutputRounded value of the given number: 2542

The log2() function of the Math object accepts a number and returns the natural logarithm (base 2) of the given number.SyntaxIts Syntax is as followsMath.log2(48);Example Live Demo    JavaScript Example           var result = Math.log2(48);       document.write("Result: "+result);     OutputResult: 5.584962500721156

The log1p() function of the Math object accepts a number and returns the natural logarithm (base E) of the (given number+1).SyntaxIts Syntax is as followsMath.log1p(48);Example Live Demo    JavaScript Example           var result = Math.log1p(48);       document.write("Result: "+result);     OutputResult: 3.8918202981106265
