ceil() - Mathematical Function
How is Mathematical Function "ceil()" used in C++?
How to find the round up value of a number?
Explanation
ceil() is a Mathematical Function returns the smallest integer value that is not less than the specified number. In other words, it returns the Round Up value of a given number.
float ceil( float num);
double ceil( double num);
long double ceil( long double num);
Result :
The ceiled value of 2.2 is:: 3
The ceiled value of -2.3 is:: -2
In the above example ceil() is used to round up the value of the number specified.
Syntax:
float ceil( float num);
double ceil( double num);
long double ceil( long double num);
Example :
| #include <stdio.h> #include <math.h> int main() { cout << "The ceiled value of 2.2 is:: " << ceil(2.2) << endl; cout << "The ceiled value of -2.3 is:: " << ceil(-2.3) << endl; return 0; } |
Result :
The ceiled value of 2.2 is:: 3
The ceiled value of -2.3 is:: -2
In the above example ceil() is used to round up the value of the number specified.
