# Mathematical Functions in VBScript

Advertisements

## Syntax :

variablename = Mathematical_function_Name(Expression)

## Description

Mathematical Functions help us to evaulate the mathematical and trigonometrical functions of a given input number.

Function | Description |
---|---|

Int | A Function, which returns the integer part of the given number |

Fix | A Function, which returns the integer part of the given number |

Log | A Function, which returns the natural logarithm of the given number. Negative numbers disallowed |

Oct | A Function, which returns the Octal value of the given percentage |

Hex | A Function, which returns the Hexadecimal value of the given number |

Rnd | A Function, which returns a random number between 0 and 1 |

Sgn | A Function, which returns a number corresponding to the sign of the specified number |

Sqr | A Function, which returns the square root of the given number. Negative numbers disallowed |

Abs | A Function, which returns the absolute value of the given number |

Exp | A Function, which returns the value of e raised to the specified number |

Sin | A Function, which returns sine value of the given number |

Cos | A Function, which returns cosine value of the given number |

Tan | A Function, which returns tan value of the given number |

## Example

Try the following example to understand all the inbuilt Mathematical Functions available in VBScript.

<!DOCTYPE html> <html> <body> <script language="vbscript" type="text/vbscript"> Dim num1 : num1 = -645.998651 Dim num2 : num2 = 210 document.write("int Result of num1 is : " & int(num1))& "<br/>" document.write("int Result of num2 is : " & int(num2))& "<br/>" document.write("Fix Result of num1 is : " & Fix(num1))& "<br/>" document.write("Fix Result of num2 is : " & Fix(num2))& "<br/>" document.write("Log Result of num2 is : " & Log(num2))& "<br/>" document.write("Oct Result of num1 is : " & Oct(num1))& "<br/>" document.write("Oct Result of num2 is : " & Oct(num2))& "<br/>" document.write("Hex Result of num1 is : " & Hex(num1))& "<br/>" document.write("Hex Result of num2 is : " & Hex(num2))& "<br/>" document.write("Rnd Result of num1 is : " & Rnd(num1))& "<br/>" document.write("Rnd Result of num2 is : " & Rnd(num2))& "<br/>" document.write("Sgn Result of num1 is : " & Sgn(num1))& "<br/>" document.write("Sgn Result of num2 is : " & Sgn(num2))& "<br/>" document.write("Sqr Result of num2 is : " & Sqr(num2))& "<br/>" document.write("Abs Result of num1 is : " & Abs(num1))& "<br/>" document.write("Abs Result of num2 is : " & Abs(num2))& "<br/>" document.write("Exp Result of num1 is : " & Exp(num1))& "<br/>" document.write("Exp Result of num2 is : " & Exp(num2))& "<br/>" document.write("Sin Result of num1 is : " & Sin(num1))& "<br/>" document.write("Sin Result of num2 is : " & Sin(num2))& "<br/>" document.write("Cos Result of num1 is : " & Cos(num1))& "<br/>" document.write("Cos Result of num2 is : " & Cos(num2))& "<br/>" document.write("Tan Result of num1 is : " & Tan(num1))& "<br/>" document.write("Tan Result of num2 is : " & Tan(num2))& "<br/>" </script> </body> </html>

When executed the above script, following is the output:

int Result of num1 is : -646 int Result of num2 is : 210 Fix Result of num1 is : -645 Fix Result of num2 is : 210 Log Result of num2 is : 5.34710753071747 Oct Result of num1 is : 37777776572 Oct Result of num2 is : 322 Hex Result of num1 is : FFFFFD7A Hex Result of num2 is : D2 Rnd Result of num1 is : 0.5130115 Rnd Result of num2 is : 0.5615935 Sgn Result of num1 is : -1 Sgn Result of num2 is : 1 Sqr Result of num2 is : 14.4913767461894 Abs Result of num1 is : 645.998651 Abs Result of num2 is : 210 Exp Result of num1 is : 2.79479883633128E-281 Exp Result of num2 is : 1.59162664037792E+91 Sin Result of num1 is : 0.920530264916375 Sin Result of num2 is : 0.467718518342759 Cos Result of num1 is : 0.390671257418547 Cos Result of num2 is : -0.883877473182372 Tan Result of num1 is : 2.35627845006822 Tan Result of num2 is : -0.529166691689464
