*  =============
*>
*> \verbatim
*>
*> This subroutine translated from a character string specifying an
*> intermediate precision to the relevant BLAST-specified integer
*> constant.
*>
*> ILAPREC returns an INTEGER.  If ILAPREC < 0, then the input is not a
*> character indicating a supported intermediate precision.  Otherwise
*> ILAPREC returns the constant value corresponding to PREC.
