=====floor=====
Syntax:

<code>
    #include <cmath>
    double floor( double arg );
</code>
The function floor() returns the largest integer not greater than arg. For
example,

<code>
     y = 6.04;
     x = floor( y );
</code>
would result in x being set to 6.0, and
<code>
     y = -6.04;
     x = floor( y );
</code>
would result in x being -7.0.

C++ also provides the following overloaded forms:
<code>
    #include <cmath>
    float floor( float arg ); // same as floorf() in C99
    long double floor( long double arg ); // same as floorl() in C99
</code>
