  • Abstract
    A technique for computing monotonicity preserving approximations Fa(x) of a function F(x) is presented. This technique involves computing an extra precise approximation of F(x) that is rounded to produce the value of Fa(x). For example, only a few extra bits of precision are used to make the accurate transcendental functions found on the Cyrix FasMath line of 80387 compatible math coprocessors monotonic
