VB.NET Pow Example – Code Sample Syntax
VB.NET Pow Example – Code Sample Syntax
Purpose: – Illustrates using VB.NET Pow Code Example.
Purpose:
takes two double data type numbers and raises the
first number to the power of the second. The result is
returned as a double data type.
Syntax:
Pow(doublenumberbase, doublenumberpower)
Pow(doublenumberbase, doublenumberpower)
Parameters | Description | doublenumberbase | Any valid System.Double data type number This is the number that will raised to the power specified in the second parameter |
---|---|
doublenumberpower | Any valid System.Double data type number This is the number that used as the power to be applied to the first parameter |
Result Data Type | Description | double | returns the first parameter raised to the power of the second input parameter |
---|
Step 1: Click Visual Basic to Cut-n-paste code into clsPow.vb
