@AmpBenzScientist i took a look at the RISC-V ISA docs and, "huh, everything actually makes sense. this is logical."

i posted this little C code riddle earlier. so here's what it does:

1. flip all the bits in the input, so 0 becomes 1 and 1 becomes 0

2. bitwise-AND this with 1, whose binary representation is also 1. this will keep only the last bit of the number and set the rest to 0.

the result can thus only be 0 or 1. if you count in binary:

0 = ...000
1 = ...001
2 = ...010
3 = ...011
4 = ...100
5 = ...101

notice how the last bit keeps flipping for every number?

if the function was just x & 1, this would tell you if the number was odd. but if you flip all the bits before you mask it, it tells you if the number is even.

could also be written as !(x & 1)
