Re: CDC Floating point = tests?

APL automatically did a fuzzy compare of real numbers based on the machine precision;
That code was implented in Fortran by me seveal years ago. If this is what you mean,
see:
http://ftp.cac.psu.edu/pub/ger/fortran/hdk/eps.f90

See logical functions, TEQ, TNE, etc..

(Comments in related function, TFLOOR document the APL connectioin).

The example driver illustrates use of these logical functions.
