I want to check if the last digit of an integer is 5.
I am contemplating using the mpz_tstbit function to test for the
representation of 5 which is 0 1 0 1. The leading zero is to prevent
accidentally being detected. Any further out and the binary digits
affect the last digit.
Does anyone know any other way I can do this?
The numbers are quite large (about 300 digits) and it is already
the numbers are odd.
