*
* DESCRIPTION
* The MAX macro returns the greater of two values.
*
* SYNOPSIS
* MAX( x, y );
*
* PARAMETERS
* x
* [in] First of two values to compare.
*
* y
* [in] Second of two values to compare.
*
* RETURN VALUE
* Returns the greater of the x and y parameters.
*
* SEE ALSO

* SYNOPSIS
* MIN( x, y );
*
* PARAMETERS
* x
* [in] First of two values to compare.
*
* y
* [in] Second of two values to compare.

/****d* Component Library: Math/ROUNDUP
* NAME
* ROUNDUP
*
* DESCRIPTION
* The ROUNDUP macro rounds a value up to a given multiple.
*
* SYNOPSIS
* ROUNDUP( val, align );
*
* PARAMETERS
* val
* [in] Value that is to be rounded up. The type of the value is
* indeterminate, but must be at most the size of a natural integer
* for the platform.
*
* align
* [in] Multiple to which the val parameter must be rounded up.
*
* RETURN VALUE
* Returns a value that is the input value specified by val rounded up to
* the nearest multiple of align.
*
* NOTES
* The value provided must be of a type at most the size of a natural integer.
