Functions
		acos(...) acos(x)   Return the arc cosine (measured in radians) of x. asin(...) asin(x)   Return the arc sine (measured in radians) 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. ceil(...) ceil(x)   Return the ceiling of x as a float. This is the smallest integral value >= x. cos(...) cos(x)   Return the cosine of x (measured in radians). cosh(...) cosh(x)   Return the hyperbolic cosine of x. degrees(...) degrees(x) -> converts angle x from radians to degrees exp(...) exp(x)   Return e raised to the power of x. fabs(...) fabs(x)   Return the absolute value of the float x. 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. hypot(...) hypot(x,y)   Return the Euclidean distance, sqrt(x*x + y*y). ldexp(...) ldexp(x, i) -> x * (2**i) log(...) log(x[, base]) -> the logarithm of x to the given base. If the base not specified, returns the natural logarithm (base e) of x. log10(...) log10(x) -> the base 10 logarithm of x. modf(...) modf(x)   Return the fractional and integer parts of x.  Both results carry the sign of x.  The integer part is returned as a real. pow(...) pow(x,y)   Return x**y (x to the power of y). radians(...) radians(x) -> converts 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.
