Enum FloatOrder 

pub enum FloatOrder {
    Greater,
    GreaterEqual,
    Less,
    LessEqual,
    LessGreater,
    Unordered,
}

A quiet floating-point comparison: __builtin_isgreater and its relatives.

“Quiet” is the whole point of them — C99 7.12.14 defines each as the comparison it names without raising the invalid exception on a NaN, which < and friends would. Rust’s floating comparison operators are the quiet ones, so each is written out as the operator it stands for.

Variants

Greater

__builtin_isgreater

GreaterEqual

__builtin_isgreaterequal

Less

__builtin_isless

LessEqual

__builtin_islessequal

LessGreater

__builtin_islessgreater: x < y || x > y, which is x != y without the NaN case.

Unordered

__builtin_isunordered: either operand is a NaN.
