Mathematical Functions in VBScript
Syntax
variablename = Mathematical_function_Name(Expression)
Mathematical Functions help us to evaluate the mathematical and trigonometrical functions of a given input number.
| Sr.No | Function & Description |
|---|---|
| 1 | Int A Function, which returns the integer part of the given number |
| 2 | Fix A Function, which returns the integer part of the given number |
| 3 | Log A Function, which returns the natural logarithm of the given number. Negative numbers disallowed |
| 4 | Oct A Function, which returns the Octal value of the given percentage |
| 5 | Hex A Function, which returns the Hexadecimal value of the given number |
| 6 | Rnd A Function, which returns a random number between 0 and 1 |
| 7 | Sgn A Function, which returns a number corresponding to the sign of the specified number |
| 8 | Sqr A Function, which returns the square root of the given number. Negative numbers disallowed |
| 9 | Abs A Function, which returns the absolute value of the given number |
| 10 | Exp A Function, which returns the value of e raised to the specified number |
| 11 | Sin A Function, which returns sine value of the given number |
| 12 | Cos A Function, which returns cosine value of the given number |
| 13 | 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.
