to_int - convert a float or buffer to an int

int to_int( float | buffer x );

If  'x'  is a float, the to_int() call returns the number of type 'int'
that is equivalent to 'x' (with any decimal stripped off).  If 'x' is a
buffer,  the  call  returns the integer (in network-byte-order) that is
embedded in the buffer.
