Decimal floating point floats are exactly as weird as binary floating points. The only difference is that different numbers are representible. You still have: - They do not obey mathematical laws for real numbers - Equality comparison is meaningless - Multiple operation lead to unboundedly large errors >Experts that handle applications with "real" numbers can then explicitly switch to "weird float". It is worth a thought. The weirdness does not go away in decimal floats. It is exactly as weird. >One could argue that for many use cases (most spreadsheets handling money amounts, for example) computers are powerful enough now that "non-integer numbers" should default to some base-10 floating point Base 10 floats do not fix money amounts. (1/3)3 is not* equal to 1 in base 10 floats. You can not correctly handle money with floats, as money is not arbitrarily dividable. Changing to base 10 does not fix that. The core problem with money is that the divison operation is not well defined. As for example $3.333... is not an amount of money that can exist. Even the mathematically correct operations are wrong, you can not fix that with imperfect approximations.
