Pow - method of the Pm object
Description:
Computes the value of "x raised to the power of y".
Syntax:
Double Pow(Double nX, Double nY)
Parameters:
| nX | (Double) Base number |
|---|
| nY | (Double) Requested exponent |
|---|
Note:
This method is functional also in
Macro expression $.expr and in the
onDraw event of the
PmgCanvas object.
This method is also functional in
Web panels.
If the computation results in a complex number, then the method returns the
NaN value (it can be tested by the
Pm.IsValid method). This means that in reality the
nX should not be a negative number.
The high value of the
nY exponent may easily lead to floating-point overflow and returns the
Infinity value.
Example:
JavaScriptVBScriptSelect and copy to clipboard
var val;
val = Pm.Pow(3, 2);
// Returns 9
val = Pm.Pow(3, 1 / 3);
// Returns "third root of three"
val = Pm.Pow(-1, 0.5);
// Returns NaN
Dim val
val = Pm.Pow(3, 2)
' Returns 9
val = Pm.Pow(3, 1 / 3)
' Returns "third root of three"
val = Pm.Pow(-1, 0.5)
' Returns NaN
