[Valgrind-users] VG_(message) floating points

[Domingues L. F. <Lui...@ed...>]

Hello,

On a tool, I try to print on the stdout the value of a floating point.
But when I use the %f formating in VG(printf) or VG_(message) it print
my string, but not my float/double.

It is a bug? Or there are another way to print floating points?

Regards,
Luis Domingues

It's a missing feature. Search the valgrind-developers mailing list for
a thread entitled "VG_(printf) '%f' patch" which was meant to add
support for printing floating point numbers. But it was never integrated
into the source tree (not sure why; perhaps a license issue).
The patch may solve your problem.
