Better output of compound units?

Open le-migou opened this issue 7 years ago • 3 comments

In v3.0.0.alpha-2, this

auto P = 1_MPa;
std::cout << P << '\n';

gives

1e+06 m^-1 kg s^-2

. Wouldn't something like

std::cout << P.value () << ' ' << abbreviation (P) << '\n';

that produces

1 MPa

be preferable ?

Seems like a bug that it doesn't print the latter. If it has an UDL, then the abbreviation should be printed. But your output suggests that the streaming operator for ephemeral units is being used.

definitely a bug.

Seems like #146 and this were fixed by #167, so in the v3.x branch the output is as expected. -- https://github.com/nholthaus/units/issues/195#issuecomment-429398567
