#Working with Mathematical Functions

C Language:
ceil function in c (Ceiling)
In the C Programming Language, the ceil function returns the smallest integer that is greater than or equal to x (ie: rounds up the nearest integer).

Syntax
The syntax for the ceil function in the C Language is:
double ceil(double x);

C Language: floor function
(Floor)
