Floating point calculations are usually imprecise, so asking if two values are exactly equal is asking for trouble"""
|
Not every floating point value can be represented exactly in binary values in
|
||||||
|
memory. Take a look at the description of
|
||||||
|
https://doc.rust-lang.org/stable/std/primitive.f32.html
|
||||||
|
When using the binary compare operators with floating points you won't compare
|
||||||
|
the floating point values but the binary representation in memory. This is
|
||||||
|
usually not what you would like to do.
|
||||||
|
See the suggestions of the clippy warning in compile output and use the
|
||||||
|
machine epsilon value...
