Since there was discussion about RealField, comparing floats for equality is considered security vulnerability:
https://cwe.mitre.org/data/definitions/1077.html Numeric calculation using floating point values can generate imprecise results because of rounding errors. As a result, two different calculations might generate numbers that are mathematically equal, but have slightly different bit representations that do not translate to the same mathematically-equal values. As a result, an equality test or other comparison might produce unexpected results. This issue can prevent the product from running reliably. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
