atanh(x) atanh returns the inverse hyperbolic tangent of x.
cbrt(x) Cbrt returns the cube root of x.
expm1(x) Expm1 returns e**x - 1, the base-e exponential of x minus 1.
It is more accurate than Exp(x) - 1 when x is near zero.
inf(x) Inf returns positive infinity if sign >= 0, negative infinity if sign < 0.
sqrt(x) Sqrt returns the square root of x.

mod(x, y) Mod returns the floating-point remainder of x/y.  The magnitude of the
result is less than y and its sign agrees with that of x.

determine the quadrant of the return value.
exp2(x) Exp2 returns 2**x, the base-2 exponential of x.
floor(x) Floor returns the greatest integer value less than or equal to x.
roundtoeven(x) RoundToEven returns the nearest integer, rounding ties to even.
