30: *>
31: *> \verbatim
32: *>
33: *> This subroutine translated from a character string specifying an
34: *> intermediate precision to the relevant BLAST-specified integer
35: *> constant.
36: *>
37: *> ILAPREC returns an INTEGER. If ILAPREC < 0, then the input is not a
38: *> character indicating a supported intermediate precision. Otherwise
39: *> ILAPREC returns the constant value corresponding to PREC.
