=====ceil=====
Syntax:

<code>
    #include <cmath>
    double ceil( double num );
</code>
The ceil() function returns the smallest integer no less than num. For example,

<code>
     y = 6.04;
     x = ceil( y );
</code>
would set x to 7.0.

C++ also provides the following overloaded forms:
<code>
    #include <cmath>
    float ceil( float num ); // same as ceilf() in C99
    long double ceil( long double num ); // same as ceill() in C99
</code>
