    Math buttons: When updating the bits panel, shift a 1ULL instead of a 1LL
    
    The 1 needs to be unsigned to be shifted by 63 positions properly.
    The behaviour is undefined otherwise.
    
    I found this with ASan:
    math-buttons.c:610:25: runtime error: left shift of 1 by 63 places cannot be represented in type 'long 
long int'
