decimal.Context.subtract()

subtract(x, y) Return the difference between x and y.

decimal.Context.sqrt()

sqrt(x) Square root of a non-negative number to context precision.

decimal.Context.shift()

shift(x, y) Returns a shifted copy of x, y times.

decimal.Context.scaleb()

scaleb(x, y) Returns the first operand after adding the second value its exp.

decimal.Context.same_quantum()

same_quantum(x, y) Returns True if the two operands have the same exponent.

decimal.Context.rotate()

rotate(x, y) Returns a rotated copy of x, y times.

decimal.Context.remainder_near()

remainder_near(x, y) Returns x - y * n, where n is the integer nearest the exact value of x / y (if the result is 0 then its sign will be the sign of x).

decimal.Context.remainder()

remainder(x, y) Returns the remainder from integer division. The sign of the result, if non-zero, is the same as that of the original dividend.

decimal.Context.radix()

radix() Just returns 10, as this is Decimal, :)

decimal.Context.quantize()

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