Description
What it does
This lint warns of misleading floating-point literals.
In the example, a has type i32 because floating-point literals must start with a decimal literal.
Instead of suffixes, we should use type ascriptions.
Lint Name

Category
style
Advantage
- Avoid ambiguity
Drawbacks
none
Example
let a = 0x1_f32; // == 0x1F32
Could be written as:
let a = 0x1 as f32;
