PWRD
Function
PWRD(860) raises the double-precision (64-bit) floating-point number in words B to B+3 to the power of
the double-precision (64-bit) floating-point number in words E to E+3. In other words, PWR(840)
calculates XY (X = content of B to B+3; Y = content of E to E+3).
For example, when the base words (B to B+3) contain 3.1 and the exponent words (E to E+3) contain 3,
the result is 3.13 or 29.791.
