CWE-1077 — Floating Point Comparison with Incorrect Operator
CWE-1077: Floating Point Comparison with Incorrect Operator
MITRE CWE weakness
| Kind | Weakness |
| Abstraction | Variant |
| Status | Incomplete |
| Likelihood of exploit | — |
Description
The code performs a comparison such as an equality test between two float (floating point) values, but it uses comparison operators that do not account for the possibility of loss of precision.
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.
