Hi !
Everybody knows that 2 power 64 equals to 18446744073709551616 ...
I defined a variable:quint64 x = 1 << 63;
When I hover over x, VS2015 tells me: 18446744071562067968
We agree that x equals to 2 power 63. So what VS gives is wrong.
Could you help please ?
Thanks. 
Ok, I forgot that ! Thanks a lot
