The pwr() function raises a value contained in an expression to the power of the value of a second expression.
Syntax
|
pwr(num.exp, power.exp) |
Parameter(s)
|
num.exp |
Value to raise to the power of the value of power.exp. |
|
power.exp |
Value whose power is applied to the value of num.exp. |
Description
A power.exp of 0 always returns a 1. A num.exp of 0 returns a 0.
As with all functions that require numeric expressions, if any of the arguments evaluate to a nonnumeric value, this run-time warning message displays:
|
[b16] in program "pgm", line n: Nonnumeric data when numeric required; zero used. |
Example(s)
This statement prints a 9, the result of 3 taken to the power of 2.
|
print pwr(3,2) |
In this statement, 3^2 is identical to pwr(3,2).
|
print 3^2 |
This statement prints the square root of the value stored in the variable xyz. This is equivalent to: print sqrt(xyz)
|
print pwr(xyz,.5) |
