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

The log10() function of the Math object accepts a number and returns the natural logarithm (base 10) of the given number.SyntaxIts Syntax is as followsMath.log10(48);Example Live Demo    JavaScript Example           var result = Math.log10(48);       document.write("Result: "+result);     OutputResult: 1.6812412373755872

The imul() function of the Math object accepts two numbers and returns the result of C-like 32-bit multiplication of the given numbers.SyntaxIts Syntax is as followsMath.imul(47, 56);Example Live Demo    JavaScript Example           var result = Math.imul(47, 56);       document.write("Result: "+result);     OutputResult: 2632

The hypot() function of the Math object accepts numbers and returns the square root of the sum of squares of the given numbers.SyntaxIts Syntax is as followsMath.hypot(12, 58, 66);Example Live Demo    JavaScript Example           var result = Math.hypot(12, 58, 66);       document.write("hypot value: "+result);     Outputhypot value: 88.67919710958147

The fround() function of the Math object accepts a floating point number and returns the nearest 32-bit single precision float representation of a Number. If the given number itself is an integer this function returns the same.SyntaxIts Syntax is as followsMath.fround(160.98)Example Live Demo    JavaScript Example           var result = Math.fround(160.98);       document.write("Fround value: "+result);     OutputFround value: 160.97999572753906
