Syntax: @GAMMA(X)
X = a numeric value
@GAMMA returns the value of the Euler's gamma function evaluated for values of X > 0, and less than or equal to approximately 171 (less on a few computers with limited mathematics capabilities). Gamma is a continuous function whose value for integer arguments N is (N1)! (N1 factorial). The function is given by:
Examples:
@GAMMA(5) = 24
@GAMMA(1.59) = 0.89243
@GAMMA(L38) = Error - @GAMMA, floating exception, where L8 = 175
