Purpose:

!>
!> 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.
