Thanks Steve (etc) ... I wonder if it's worth filing a bug about expf in particular; I dunno whether that change is isolated enough to make a patch easy... Based on a glance at the source, it seems like the math libraries were changed in lots of little ways between 2.13 and 2.16 [and it looks like the FPU-twiddling that made expf slow in 2.13 has been _added_ to the generic version of the "exp" (double-precision) function, meaning it might actually be (much) _slower_ in 2.16 on ports without optimized implementations... :( ] -miles -- Carefully crafted initial estimates reward you not only with reduced computational effort, but also with understanding and increased self-esteem. -- Numerical methods in C, Chapter 9.
