hi！ bil til

Thanks for your answer！

but I want to know what is this place

return hashmod(t, cast_int(ui)); //------------------------------------------

Why do you want to use `cast_int(ui)`

such a cast typically does not produce code in assembler...

it is just an instruction for the compiler, to use the correct
comparison operator (in this case "unsigned <= unsigned").

If you would not do such casting, in "best case" you would get C
compiler warnings or errors - in worst case severe
"misunderstandings"... .
