Given that the list seems to be bde and myself, and bde sticks to technical details on steroids, I suppose I should take this as a comment. Oh, the irony. > But at least you will get a good sense of what is needed, and > also how overly exacting their standards are. Overly exacting? If you make your living doing numerical computations and you use libm, don't you want the functions in that library to give you high quality results? BTW, if you look at the patch, the long double complex functions will have at least 2**11 ULP error on i686-class hardware (i.e.,=20 that last 4 to 6 decimal digits are likely wrong). See the ld80 routines that use LD80C to set constants and ENTERI and RETURNI to toggle the FPU precision. --=20 You are receiving this mail because: You are the assignee for the bug.=
