`This module is always available. It provides access to the
mathematical functions defined by the C standard.`

Functions
`` |  | acos(...) `acos(x) Return the arc cosine (measured in radians) of x.` acosh(...) `acosh(x) Return the inverse hyperbolic cosine of x.` asin(...) `asin(x) Return the arc sine (measured in radians) of x.` asinh(...) `asinh(x) Return the inverse hyperbolic sine of x.` atan(...) `atan(x) Return the arc tangent (measured in radians) of x.` atan2(...) `atan2(y, x) Return the arc tangent (measured in radians) of y/x. Unlike atan(y/x), the signs of both x and y are considered.` atanh(...) `atanh(x) Return the inverse hyperbolic tangent of x.` ceil(...) `ceil(x) Return the ceiling of x as a float. This is the smallest integral value >= x.` copysign(...) `copysign(x, y) Return x with the sign of y.` cos(...) `cos(x) Return the cosine of x (measured in radians).` cosh(...) `cosh(x) Return the hyperbolic cosine of x.` degrees(...) `degrees(x) Convert angle x from radians to degrees.` erf(...) `erf(x) Error function at x.` erfc(...) `erfc(x) Complementary error function at x.` exp(...) `exp(x) Return e raised to the power of x.` expm1(...) `expm1(x) Return exp(x)-1. This function avoids the loss of precision involved in the direct evaluation of exp(x)-1 for small x.` fabs(...) `fabs(x) Return the absolute value of the float x.` factorial(...) `factorial(x) -> Integral Find x!. Raise a ValueError if x is negative or non-integral.` floor(...) `floor(x) Return the floor of x as a float. This is the largest integral value <= x.` fmod(...) `fmod(x, y) Return fmod(x, y), according to platform C. x % y may differ.` frexp(...) `frexp(x) Return the mantissa and exponent of x, as pair (m, e). m is a float and e is an int, such that x = m * 2.**e. If x is 0, m and e are both 0. Else 0.5 <= abs(m) < 1.0.` fsum(...) `fsum(iterable) Return an accurate floating point sum of values in the iterable. Assumes IEEE-754 floating point arithmetic.` gamma(...) `gamma(x) Gamma function at x.` hypot(...) `hypot(x, y) Return the Euclidean distance, sqrt(x*x + y*y).` isinf(...) `isinf(x) -> bool Check if float x is infinite (positive or negative).` isnan(...) `isnan(x) -> bool Check if float x is not a number (NaN).` ldexp(...) `ldexp(x, i) Return x * (2**i).` lgamma(...) `lgamma(x) Natural logarithm of absolute value of Gamma function at x.` log(...) `log(x[, base]) Return the logarithm of x to the given base. If the base not specified, returns the natural logarithm (base e) of x.` log10(...) `log10(x) Return the base 10 logarithm of x.` log1p(...) `log1p(x) Return the natural logarithm of 1+x (base e). The result is computed in a way which is accurate for x near zero.` modf(...) `modf(x) Return the fractional and integer parts of x. Both results carry the sign of x and are floats.` pow(...) `pow(x, y) Return x**y (x to the power of y).` radians(...) `radians(x) Convert angle x from degrees to radians.` sin(...) `sin(x) Return the sine of x (measured in radians).` sinh(...) `sinh(x) Return the hyperbolic sine of x.` sqrt(...) `sqrt(x) Return the square root of x.` tan(...) `tan(x) Return the tangent of x (measured in radians).` tanh(...) `tanh(x) Return the hyperbolic tangent of x.` trunc(...) `trunc(x:Real) -> Integral Truncates x to the nearest Integral toward 0. Uses the __trunc__ magic method.`
