# math

# math.pi


# math.e


# math.inf

The inf.

# math.nan

The nan.

# math.ceil(x)

Return the ceiling of x as a float, the smallest integer value greater than or equal to x.

# math.fabs(x)

Return the absolute value of x.

# math.floor(x)

Return the floor of x as a float, the largest integer value less than or equal to x.

# math.fsum(iterable)

Return an accurate floating point sum of values in the iterable. Avoids loss of precision by tracking multiple intermediate partial sums:

>>> sum([0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1])
>>> fsum([0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1])

# math.gcd(a, b)

Return the greatest common divisor of the integers a and b.

# math.isfinite(x)

Return True if x is neither an infinity nor a NaN, and False otherwise.

# math.isinf(x)

Return True if x is a positive or negative infinity, and False otherwise.

# math.isnan(x)

Return True if x is a NaN (not a number), and False otherwise.

# math.exp(x)

Return e raised to the power of x.

# math.log(x)

Return the natural logarithm of x (to base e).

# math.log2(x)

Return the base-2 logarithm of x. This is usually more accurate than log(x, 2).

# math.log10(x)

Return the base-10 logarithm of x. This is usually more accurate than log(x, 10).

# math.pow(x, y)

Return x raised to the power y.

# math.sqrt(x)

Return the square root of x.

# math.acos(x)

Return the arc cosine of x, in radians.

# math.asin(x)

Return the arc sine of x, in radians.

# math.atan(x)

Return the arc tangent of x, in radians.

# math.atan2(y, x)

Return atan(y / x), in radians. The result is between -pi and pi. The vector in the plane from the origin to point (x, y) makes this angle with the positive X axis. The point of atan2() is that the signs of both inputs are known to it, so it can compute the correct quadrant for the angle. For example, atan(1) and atan2(1, 1) are both pi/4, but atan2(-1, -1) is -3*pi/4.

# math.cos(x)

Return the cosine of x radians.

# math.sin(x)

Return the sine of x radians.

# math.tan(x)

Return the tangent of x radians.

# math.degrees(x)

Convert angle x from radians to degrees.

# math.radians(x)

Convert angle x from degrees to radians.

# math.modf(x)

Return the fractional and integer parts of x. Both results carry the sign of x and are floats.

# math.factorial(x)

Return x factorial as an integer.
