Operator represents specific mathematical or logical actions in programming. Operators manipulate operands to generate specific results. Operators differ from system operators, which operate computing systems
sqrt() returns square root of a number in C. Function is defined in math.h header file. Takes single double parameter as input
Python's built-in functions don't include sign function since version 3.11. Developers chose copysign() in math module for edge cases. Float type treats 0.0 and -0.0 as distinct objects
Computes standard deviation along specified axis for array elements. Default behavior is flattened array calculation. Supports multiple axes calculation for tuples of ints
INT returns integer part of a number by rounding down. Function takes only one numeric argument. Returns #VALUE! error for non-numeric inputs
Module exports efficient functions for Python's intrinsic operators. Functions fall into categories: comparisons, logical, mathematical, and sequence operations. Many function names are special method names without double underscores
