Print Double Precision Values

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
