Expn

Type Function: REAL

Input X	REAL (input)
N	INT (exponential)
Output	REAL (result X^N)
	EXPN calculates the exponential value of X^N for integer N. EXPN is especifically written for PLC without Floating Point Unit and is about 30 times faster than the IEC standard function EXPT(). Note the special case of the 0^0 defined mathematically as a 1 and is not a 0.
EXPN(10,-2) = 0.01	EXPN(1.5,2) = 2.25
	EXPN(0,0) = 1
