Bug ID: 118231
Summary: _Decimal32 datatype fails with 'cannot mix operands',
where _Decimal64 and _Decimal128 hold,
Product: gcc
Version: 13.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: newbie-02 at gmx dot de
Target Milestone: ---
hello @ all,
pls. check if I'm in error ( alas always an option ), or the compile error with
the following snipped belongs to another part of the workbench ( glibc? ).
The error is noted in the file, my gcc version is: gcc (Debian 13.3.0-6) 13.3.0
.
```
#define __STDC_WANT_DEC_FP__
#define __STDC_WANT_IEC_60559_DFP_EXT__
#include <stdio.h>
// reg. e.g. printf,
int main( int argc, char *argv[] )
{
volatile _Decimal32 x1D = 1.0D, x2D = 1.0D, x3D = 1.0D;
volatile _Decimal64 x1DD = 1.0DD, x2DD = 1.0DD, x3DD = 1.0DD;
volatile _Decimal128 x1DL = 1.0DL, x2DL = 1.0DL, x3DL = 1.0DL;
printf( "'x1D = 1.0D / x1D;' -> error: cannot mix operands of decimal
floating and other floating types \n" );
printf( "no problem with x3DD = 1.0DD / x1DD and x3DL = 1.0DL / x1DL,
\n" );
x3D = 1.0D / x1D;
// uncommenting this line produces compile error,
x3DD = 1.0DD / x1DD;
x3DL = 1.0DL / x1DL;
return 0;
}
```
TIA for any hint, best wishes for next year ... Bernhard
