*> \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.
