quantize(x, y) Returns a value equal to x (rounded), having the exponent of y.

normalize(context=None) Normalize the number by stripping the rightmost trailing zeros and converting any result equal to

math.log1p(x) Return the natural logarithm of 1+x (base e). The result is calculated in a way which is accurate

remainder_near(other, context=None) Return the remainder from dividing self by other. This differs from self

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

random.gauss(mu, sigma) Gaussian distribution. mu is the mean, and sigma is the standard deviation. This is

random.lognormvariate(mu, sigma) Log normal distribution. If you take the natural logarithm of this distribution, you’ll get
