PARANOIA - A FORTRAN version of Kahan's Floating Point Test

PARANOIA is 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.

There is also a C version of this program.
