C provides many functions that allow you to perform mathematical tasks on numbers.

Math Header

To use these functions, you must add the #include <math.h> header file.

Common Functions

• sqrt(x): Returns the square root of x
• ceil(x): Rounds x upwards to the nearest integer
• floor(x): Rounds x downwards to the nearest integer
• pow(x, y): Returns the value of x to the power of y
• abs(x): Returns the absolute value of x
