* operator has has a higher precedence than <<
==============================================
## Copyright (C) 1999-2007,2014,2017,2021 Landon Curt Noll
The * operator has has a higher precedence than <<, which differs from the C language.
So 3 << 2*5 evaluates to 3072 in C, whereas 3 << 2*5 evaluates to 60 in calc.
