Fixed a problem with precesion 0,0 0,00 (#4120)

When precesion is set to 0,0 or 0,00 and the choosen value is 1,0 or 1,00 following happens:
eins meter
This is incorrect so i coded another part in the else part of "qr.rem > 0"  that checks if qr.quot is 1. If it is following happens now:
ein meter
