Purpose:

 ZLAG2C converts a COMPLEX*16 matrix, SA, to a COMPLEX matrix, A.

 RMAX is the overflow for the SINGLE PRECISION arithmetic
 ZLAG2C checks that all the entries of A are between -RMAX and
 RMAX. If not the conversion is aborted and a flag is raised.

 This is an auxiliary routine so there is no argument checking.

Parameters

[in]	M	M is INTEGER The number of lines of the matrix A. M >= 0.
[in]	N	N is INTEGER The number of columns of the matrix A. N >= 0.
[in]	A	A is COMPLEX*16 array, dimension (LDA,N) On entry, the M-by-N coefficient matrix A.
[in]	LDA	LDA is INTEGER The leading dimension of the array A. LDA >= max(1,M).
[out]	SA	SA is COMPLEX array, dimension (LDSA,N) On exit, if INFO=0, the M-by-N coefficient matrix SA; if INFO>0, the content of SA is unspecified.
[in]	LDSA	LDSA is INTEGER The leading dimension of the array SA. LDSA >= max(1,M).
[out]	INFO	INFO is INTEGER = 0: successful exit. = 1: an entry of the matrix A is greater than the SINGLE PRECISION overflow threshold, in this case, the content of SA in exit is unspecified.
