Hello,
I am looking for information about a function that was apparently in the
older BSD math libary called fmod. It is called floating modulus in the
comments of the program we have that called it, and the usage appears to be:
double = fmod (double, double). If anyone knows what this turkey did exactly,
or has the source for it, I'd appreciate some help. Incidentally, our site has
a Berkeley source license. My address is:
ARPA: greg@cvl.umd.edu
UUCP: seismo!mimsy!cvl!greg. Please send E-mail if you have any useful
information. Thanks in advance.

Thanks in advance. > Greg Koolbeck It is actually double fmod(arg,addr) double arg; double *addr; { ... } which returned the fractional part, and stored the integer part at *addr. The only problem (I know of) with it is that if a negative number was supplied, both pieces were left negative. (may be a feature, not a bug, but it wasn't what I expected.)
