Operator ** | Xbase++ | Alaska Software

Exponential operator (binary): exponentiation of a numeric value.

<nValue> ** <nExponent>  // or
<nValue> ^ <nExponent>

<nValue> is a numeric expression whose value is to be raised exponentially (to the specified power).

<nExponent> is a numeric expression for the power (exponent) to which <nValue> is raised.

The exponential operator determines the value of <nValue> raised to the power of <nExponent> and returns the result of the operation as a numeric value.

// This example shows various results of the exponentiation operator.
