Enum rustc_apfloat::ieee::Loss

source · [−]

enum Loss {
    ExactlyZero,
    LessThanHalf,
    ExactlyHalf,
    MoreThanHalf,
}

Expand description

Enum that represents what fraction of the LSB truncated bits of an fp number represent.

This essentially combines the roles of guard and sticky bits.

Variants

`ExactlyZero`

`LessThanHalf`

`ExactlyHalf`

`MoreThanHalf`
