Berkeley SoftFloat is a software implementation of binary floating-point that
conforms to the IEEE Standard for Floating-Point Arithmetic. The current
release supports five binary formats: 16-bit half-precision, 32-bit
single-precision, 64-bit double-precision, 80-bit double-extended- precision,
and 128-bit quadruple-precision.
This version is a fork by SoftDevLabs (SDL) to support the SDL-Hercules-390
emulator.
