mathematical functions
The math module provides some basic mathematical functions for
working with floating-point numbers.
-
math.e:Any¶ base of the natural logarithm
-
math.pi:Any¶ the ratio of a circle’s circumference to its diameter
-
math.acos(x: Any) → Any¶ Return the inverse cosine of
x.
-
math.asin(x: Any) → Any¶ Return the inverse sine of
x.
-
math.atan(x: Any) → Any¶ Return the inverse tangent of
x.
-
math.atan2(y: Any, x: Any) → Any¶ Return the principal value of the inverse tangent of
y/x.
-
math.ceil(x: Any) → Any¶ Return an integer, being
xrounded towards positive infinity.
-
math.copysign(x: Any, y: Any) → Any¶ Return
xwith the sign ofy.
-
math.cos(x: Any) → Any¶ Return the cosine of
x.
-
math.degrees(x: Any) → Any¶ Return radians
xconverted to degrees.
-
math.exp(x: Any) → Any¶ Return the exponential of
x.
-
math.fabs(x: Any) → Any¶ Return the absolute value of
x.
-
math.floor(x: Any) → Any¶ Return an integer, being
xrounded towards negative infinity.
-
math.fmod(x: Any, y: Any) → Any¶ Return the remainder of
x/y.
-
math.frexp(x: Any) → Any¶ Decomposes a floating-point number into its mantissa and exponent. The returned value is the tuple
(m, e)such thatx == m * 2**eexactly. Ifx == 0then the function returns(0.0, 0), otherwise the relation0.5 <= abs(m) < 1holds.
-
math.isfinite(x: Any) → Any¶ Return
Trueifxis finite.
-

-
math.ldexp(x: Any, exp: Any) → Any¶ Return
x * (2**exp).
-
math.modf(x: Any) → Any¶ Return a tuple of two floats, being the fractional and integral parts of
x. Both return values have the same sign asx.
-
math.pow(x: Any, y: Any) → Any¶ Returns
xto the power ofy.
-
math.radians(x: Any) → Any¶ Return degrees
xconverted to radians.
-
