Math Functions

There is a list of math functions available that allow you to perform mathematical tasks on numbers.

To use them, you must include the math.h header file in your program:

#include 

Square Root

To find the square root of a number, use the sqrt() function:

printf("%f", sqrt(16));

4.000000

Round a Number

The ceil() function rounds a number upwards to its nearest integer, and the floor() function rounds a number downwards to its nearest integer and returns the result:

printf("%f", ceil(1.4));
printf("%f", floor(1.4));

2.000000
1.000000

Power

The pow() function returns the value of x to the power of y (x^y):

printf("%f", pow(4, 3));

64.000000
