log10(context=None) Return the base ten logarithm of the operand. The result is correctly rounded using the ROUND_HALF_EVEN

cmath.isinf(x) Return True if either the real or the imaginary part of x is an infinity, and False

from_float(f) Classmethod that converts a float to a decimal number, exactly. Note Decimal

statistics.stdev(data, xbar=None) Return the sample standard deviation (the square root of the sample variance). See variance()

math.pi The mathematical constant π = 3.141592..., to available precision.

min(other, context=None) Like min(self, other) except that the context rounding rule is applied before returning

min_mag(other, context=None) Similar to the min() method, but the comparison is done using the absolute values

cmath.sin(x) Return the sine of x.

conjugate() Just returns self, this method is only to comply with the Decimal Specification.

logical_xor(x, y) Applies the logical operation xor between each operand’s digits.
