mpf_class x("+0.73") aborts

[Pasquale Tricarico]

Hi,

If you include a statement in your code such as

#include <gmpxx.h>
[...]
mpf_class x("+0.73");

or any other string in the form "+XYZ", it will abort at runtime with:

terminate called after throwing an instance of 'std::invalid_argument'
  what():  mpf_set_str
Aborted

I believe that a signed string, with a plus, should be a valid
argument. The same with a minus instead of a plus is valid, as it is
an unsigned value, of course.

Comments and solutions welcome.

Regards,
Pasquale
