Operational
Python has five operational built-in functions for numeric types: abs(), coerce(), divmod(), pow(), and round(). We will take a look at each and present some usage examples.
abs() returns the absolute value of the given argument. If the argument is a complex number, then math.sqrt( num. real2 + num. imag2) is returned. Here are some examples of using the abs() built-in function:
Example
>>> abs(-1) 1 >>> abs(10.) 10.0 >>> abs(12.-2.1j) 12.182364302548173 >>> abs(0.23 - 0.78) 0.55
