--- Comment #9 from Jonathan Wakely <redi at gcc dot gnu.org> --- Please go and complain somewhere else, it's not GCC's problem that you are surprised by the behaviour of binary floating point logic. There are several ways to work with exact decimal numbers. See https://gcc.gnu.org/onlinedocs/gcc/Decimal-Float.html for one option. Another is a maths library such a GMP for working with rational numbers. Another is working with integers and scaling them in your code.
