PARANOIA
Kahan's Floating Point Test Program


PARANOIA is a FORTRAN77 program which checks properties of a computer's arithmetic.

PARANOIA is a version of a program, originally written in BASIC (!) by Professor W M Kahan, which tests the properties of the floating point arithmetic used on a computer. It is a more ambitious test than that carried out by MACHAR.

The original, true, correct version of PARANOIA is available in the PARANOIA subdirectory of the NETLIB web site.
