Enum rustc_apfloat::ieee::Loss[−][src]

#[must_use]
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

Implementations

impl Loss[src]
