Function Power(x, y)

Power

Power(
     x,      ! (input) numerical expression
     y       ! (input) numerical expression
     )

Arguments

x

A scalar numerical expression.

y

A scalar numerical expression.

Return Value

The function Power returns $x$ raised to the power $y$.

Example

_p_returnA := power( 8, 3 ); ! power( 8, 3 ) =  512
_p_returnB := power( 8,-3 ); ! power( 8,-3 ) =  0.001953125000
_p_returnC := power(-8, 3 ); ! power(-8, 3 ) =  -512
_p_returnD := power(-8,-3 ); ! power(-8,-3 ) =  -0.001953125000

Note

• The following combination of arguments is allowed:

  • $x>0$

  • $x=0$ and $y>0$

  • $x<0$ and $y$ integer

  In all other cases a run-time error will result.

• The function can be used in constraints of nonlinear mathematical programs.
