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
.
