[cfe-dev] Print Double Precision Values

[Zheng Wang]

Hi,

The VisitFloatingLiteral in StmtPrint is defined as:

        // FIXME: print value more precisely.
        OS << Node->getValueAsApproximateDouble();


This may result in lost of precision when printing double precision value.
 For example,
"-3.247834652034740e3" will be printed as "-3.247835e+03"

Is there any way to *precisely* print out a double precision value (i.e.,
the same as it appears in the source code)?


Cheers,
Zheng
