Thx for the replies everybody. No sure I really "get it" but at least I know how to make it work. (s2 existed so I could look at the values in GDB)

Having said that, how should I code this so iy happens in one step?

string s1 = to_string(z);
win2_unitprice->value(s1.c_str());

There are possibly as many answers to that as there are programmers... Opinions will vary!

FWIW I'd be using C-strings & snprintf() probably. That's not the answer you need or want.

The easiest way might be to use an Fl_Value_Input widget instead, since that will accept your double z directly without conversions at all.
