compare_total_mag(other, context=None) Compare two operands using their abstract representation rather than their value as in

is_qnan(x) Returns True if x is a quiet NaN; otherwise returns False.

is_nan(x) Returns True if x is a qNaN or sNaN; otherwise returns False.

plus(x) Plus corresponds to the unary prefix plus operator in Python. This operation applies the context precision and rounding

cmath.acosh(x) Return the inverse hyperbolic cosine of x. There is one branch cut, extending left from 1 along the

math.hypot(x, y) Return the Euclidean norm, sqrt(x*x + y*y). This is the length of the vector from the origin to

math.fsum(iterable) Return an accurate floating point sum of values in the iterable. Avoids loss of precision by tracking multiple

max_mag(x, y) Compares the values numerically with their sign ignored.

remainder_near(x, y) Returns x - y * n, where n is the integer nearest the exact value of x / y

math.atan2(y, x) Return atan(y / x), in radians. The result is between -pi and pi. The
