Invgamma
Inverse of the gamma function.
 
Loading        LOADSUB ALL FROM "GAMMA.HTS"
or LOADSUB FROM "MATHLIB.HTS"
 
Usage                REAL X,Y
Y=FNInvgamma(X)
 
Description                
FNInvgamma returns the value of 1/(x). Unlike (x), 1/(x) is defined at negative integral values of x and at x = 0. This function is provided for use in expressions that involve dividing by (x), where the regular gamma function, FNGamma, would cause Errors when evaluated at values of x equal to negative integers or zero.
 
Errors                
FNInvgamma causes an HTBasic error if its argument is not of type REAL.
