Rounding error after stock split

[Janis]

Hi Thomas,

nice, thank you so much!
I've initially encountered this on 5.1.3 but wanted to double check with the 
current master before asking. With the complete rewrite you're speaking of - 
is there any chance to get a fix "backported" to 5.1.3 (for Debian in my case)?

Cheers
Janis
