Convert between IEEE double value and Microsoft (MS) binary double value.
#include <math.h>
int _dieeetomsbin( double *src8, double *dst8 );
int _dmsbintoieee( double*src8, double*dst8 );
| src8 | Buffer containing value to convert | |
| dst8 | Buffer to store converted value |
The _dieeetomsbin routine converts a double-precision number in IEEE (Institute of Electrical and Electronic Engineers) format to Microsoft (MS) binary format. The routine _dmsbintoieee converts a double-precision number in MS binary format to IEEE format.
These routines allow C programs (which store floating-point numbers in the IEEE format) to use numeric data in random-access data files created with those versions of Microsoft Basic that store floating-point numbers in MS binary format, and vice versa.
The argument src8 is a pointer to the double value to be converted. The result is stored at the location given by dst8.
These routines do not handle IEEE NANs (“not a number”) and infinities. IEEE denormals are treated as 0 in the conversions.
These functions return 0 if the conversion is successful and 1 if the conversion causes an overflow.
