INT ilaprec(const char *prec)

This subroutine translated from a character string specifying an intermediate precision to the relevant BLAST-specified integer constant.

Parameters

in

prec

prec='S': single precision. prec='D': double precision. prec='I': indigenous precision. prec='X' or prec='E': extra precision.

Returns:

An integer. If the returned value <0, then the input is not a character indicating a supported intermediate precision. Otherwise the constant value corresponding to prec is returned: 211 (BLAS_PREC_SINGLE), 212 (BLAS_PREC_DOUBLE), 213 (BLAS_PREC_INDIGENOUS), 214 (BLAS_PREC_EXTRA).
