math – Mathematical Functions
The math module provides some basic mathematical functions for working with floating-point numbers. Floating point support required for this module.
Functions
#####math.acos(x)
Return the inverse cosine of x.
#####math.acosh(x)
Return the inverse hyperbolic cosine of x.
#####math.asin(x)
Return the inverse sine of x.
#####math.asinh(x)
Return the inverse hyperbolic sine of x.
#####math.atan(x)
Return the inverse tangent of x.
#####math.atan2(y, x)
Return the principal value of the inverse tangent of y/x.
#####math.atanh(x)
Return the inverse hyperbolic tangent of x.
#####math.ceil(x)
Return an integer, being x rounded towards positive infinity.
#####math.copysign(x, y)
Return x with the sign of y.
#####math.cos(x)
Return the cosine of x.
#####math.cosh(x)
Return the hyperbolic cosine of x.
#####math.degrees(x)
Return radians x converted to degrees.
#####math.erf(x)
Return the error function of x.
#####math.erfc(x)
Return the complementary error function of x.
#####math.exp(x)
Return the exponential of x.
#####math.expm1(x)
Return exp(x) - 1.
#####math.fabs(x)
Return the absolute value of x.
#####math.floor(x)
Return an integer, being x rounded towards negative infinity.
#####math.fmod(x, y)
Return the remainder of x/y.
#####math.frexp(x)
Decomposes a floating-point number into its mantissa and exponent. The returned value is the tuple (m, e) such that x == m * 2**e exactly. If x == 0 then the function returns (0.0, 0), otherwise the relation 0.5 <= abs(m) < 1 holds.
#####math.gamma(x)
Return the gamma function of x.
#####math.isfinite(x)
Return True if x is finite.
#####math.isinf(x)
Return True if x is infinite.
#####math.isnan(x)
Return True if x is not-a-number
#####math.ldexp(x, exp)
Return x * (2**exp).
#####math.lgamma(x)
Return the natural logarithm of the gamma function of x.
#####math.log(x)
Return the natural logarithm of x.
#####math.log10(x)
Return the base-10 logarithm of x.
#####math.log2(x)
Return the base-2 logarithm of x.
#####math.modf(x)
Return a tuple of two floats, being the fractional and integral parts of x. Both return values have the same sign as x.
#####math.pow(x, y)
Returns x to the power of y.
#####math.radians(x)
Return degrees x converted to radians.
#####math.sin(x)
Return the sine of x.
#####math.sinh(x)
Return the hyperbolic sine of x.
#####math.sqrt(x)
Return the square root of x.
#####math.tan(x)
Return the tangent of x.
#####math.tanh(x)
Return the hyperbolic tangent of x.
#####math.trunc(x)
Return an integer, being x rounded towards 0.
