Summary0026331: Windows (YYC): Bitshifting in YYC provides different results than VM
DescriptionThe project in the sample URL draws different outputs to screen depending on what target you've chosen. With windows YYC it draws 0 (which is the bug I'm making this report for), while the normal windows draws the expected number 10.89. I've been using bitshifting as a shortcut to floor(variablename / 2) and floor(variablename / (2 to the power of some number)), so returning 0 instead of half the value made my GUI buggy.
Steps To Reproduce1) Run project in VM
2) Run project in YYC

confirmed. YYC currently needs "real(b)*0.99" or "0.99*b" which isn't right.

Fixed in gitlab - YYGML.h change so could be applied in the field
