There is also a list of math functions available, that allows you to perform mathematical tasks on numbers. To use them, you must include the math.h header file in your program: ... The ceil() function rounds a number upwards to its nearest integer, and the floor() method rounds a number downwards to its nearest integer, and returns the result:

Here you can see that we have input two floating point numbers 5.26 and 3.17 and pass the values to the fmod() function. The fmod() function returned the result in the variable c after calculating the remainder of the division. Thus the final output is 2.090000. The pow() function is used to computes the power of a number. ... In mathematics the power is written as xy.
