H A DREADME.txt4 Package Overview for SoftFloat Release 2a
10 SoftFloat is a software implementation of floating-point that conforms to
11 the IEC/IEEE Standard for Binary Floating-Point Arithmetic. SoftFloat is

18 -- A `timesoftfloat' program for evaluating the speed of the SoftFloat
19 routines. (The SoftFloat module is linked into this program.)
21 The SoftFloat package is documented in four text files:
24 softfloat-source.txt Documentation for compiling SoftFloat.
25 softfloat-history.txt History of major changes to SoftFloat.
