Prove programs with floating-point or fixed-point arithmetic
Gappa is a tool intended to help verifying and formally prove properties on numerical programs and circuits handling floating-point or fixed-point arithmetic. This tool manipulates logical formulas stating the enclosures of expressions in some intervals. Through the use of rounding operators as part of the expressions, Gappa is specially designed to deal with formulas that could appear when certifying numerical codes. In particular, Gappa makes it simple to bound computational errors due to floating-point arithmetic. The tool and its documentation were written by Guillaume Melquiond.
