primes.fs 30Nov04 13:37:08EST 3.3K A commented version of Eratosthenes' sieve, designed for viewing primes in a range.

ttester and xftester
ttester.fs Anton Ertl's ttester.fs extends the original Hayes tester to floating point, including some ideas from ftester-old.fs, and adds support for an integrated floating point stack. Tests preserve initial stacks. It works on ANS Forth systems with or without floating point, and with or without an integrated stack. Consult the gforth CVS link at left for history and probably the newest version.
ttester-xf.fs 06Feb21 09:53:56EST 21K A revision of ttester restricted to a separate floating-point stack. With some restrictions on the words used, it remains compatible with ttester. It does overflow checking for initial, resultant, and goal stack storage, with configurable limits. Error reporting and approximate equality continue to be vectorized, as with ttester, but with independent error reporting for the two stacks. Starting with version 1.4.0, deepest errors are found first, corresponding to the usual left to right order of stack pictures, which is also the order of execution that produces them.

27Jan21 12:04:11EST
A small library that translates between raw32, raw64, raw80, or raw128 formats on the data stack or in memory and the corresponding default, machine-native encoding on the floating-point stack. The numbers in the names refer to the width of the native encoding in bits. The raw format gives access to the bits of the encoding in a style compatible with Forth conventions for multi-cell integers, which is convenient for shifting and masking, and fairly convenient for hex data display and entry. The tests require ttester.fs or ttester-xf.fs. Works for big/little-endian and 32/64-bit systems.
27Jan21 12:05:16EST
27Jan21 12:05:16EST
Contains the rawfloat library above and adds translations betweem the four raw formats and Forth string formats giving faithful representations of the exactly 8, 16, 20, and 32 hex digits of the corresponding native encodings. It also does translation between the default floating-point stack encoding and the hex string format corresponding to its width. Works for big/little-endian and 32/64-bit systems. The tests work either with ttester.fs or with ttester-xf.fs.
