Static rustc_lint::types::INVALID_NAN_COMPARISONS
source · static INVALID_NAN_COMPARISONS: &Lint
Expand description
The invalid_nan_comparisons
lint checks comparison with f32::NAN
or f64::NAN
as one of the operand.
Example
let a = 2.3f32;
if a == f32::NAN {}
{{produces}}
Explanation
NaN does not compare meaningfully to anything – not even itself – so those comparisons are always false.
