as I understand the code it computes the fractional part of a/b. modf 
returnes the fractional part of the 1st argument (and stores the 
integer part in the 2nd.) So modf(a/b,NULL) is the straight-forward 
translation of the task as I read it.

When a parameter is exspected and one wants it to be NULL, it must of 
course be posted on the stack.

(Quiet, Brownie! don't break the peace, now!) I don't mean to complain 
about anything. I just try to understand.

So long, have a nice day!
