Also it's working on global variables x and y, not on the variables that's passed to the function. Replace it with: function pow_udf(m, n:real) : real; begin pow_udf:= exp(n * ln(m)); end; share|improve this answer answered Sep 12 '13 at 18:13 Sertac Akyuz 40.9k359108 pow_udf is some kind of "variable", am I right?
