/*
 * SpanDSP - a series of DSP components for telephony
 *
 * floating_fudge.h - A bunch of shims, to use double maths
 *                    functions on platforms which lack the
 *                    float versions with an 'f' at the end,
 *                    and to deal with the vaguaries of lrint().
