Module rvsim::softfloat[−][src]

Berkeley SoftFloat bindings.

These are partial bindings, and only part of the SoftFloat package is actually linked into the library. Some of the names have been altered to be more in line with Rust naming.

Structs

Sf32	A single-precision soft-float. Internally represented as `u32`.
Sf64	A double-precision soft-float. Internally represented as `u64`.

Constants

FLAG_INEXACT	Inexact result exception.
FLAG_INFINITE	Result is infinity (division by zero).
FLAG_INVALID	Invalid operation (result is NaN).
FLAG_OVERFLOW	Overflow exception.
FLAG_UNDERFLOW	Underflow exception.
ROUND_MAX	Round towards +∞.
ROUND_MIN	Round towards -∞.
ROUND_MIN_MAG	Round towards 0.
ROUND_NEAR_EVEN	Round to nearest, ties to even.
ROUND_NEAR_MAXMAG	Round to nearest, ties away from 0.
