	abs, acos asin, atan, atan2, ceil, cos, cosh, exp, fabs, floor, fmod, frexp, ldexp, log, log10, modf, pow, sin, sinh, sqrt, tan, tanh, signbit, fpclassify, isfinite, isinf, isnan, isnormal, isgreater, isgreaterequal, isless, islessequal, islessgreater, isunordered, acosh, asinh, atanh, cbrt, copysign, erf, erfc, exp2, expm1, fdim, fma, fmax, fmin, hypot, ilogb, lgamma, llrint, llround, log1p, log2, logb, lrint, lround, nearbyint, nextafter, nexttoward, remainder, remquo, rint, round, scalbln, scalbn, tgamma, trunc
