Simon Brooke 46a4132823 Made it easier to run individual unit tests 2019-01-18 20:55:03 +00:00
Simon Brooke 7f93b04b72 Various refactorings around bignum arithmetic 2019-01-17 17:04:14 +00:00
Simon Brooke d624c671cd Major refactoring, all tests still pass 
Bignum issues not yet folly resolved.

Simon Brooke 67443e1d46 OK, adding bignums works; multiplying bignums does not work. 
There's no evidence of a bug in reading/printing, because the only way I can currently get a number big enough to trigger the supposed bug is by multiplying, which doesn't work.

Simon Brooke 67802a07b8 Now successfully reading/printing 2 cell bignums 
Something is wrong with n-cell bignums, but let's make haste slowly.

Simon Brooke d9d789fdd0 Now creating the correct internal bignum representation 
add_integers returns an integer which by inspection of the internal representation is correct, but the print representation is not correct.

Simon Brooke 4295b6e57f This isn't working, but it's VERY promising. 2019-01-01 15:04:44 +00:00
Simon Brooke 6d2cf313cb Very small fix to formatting integers. 2018-12-31 16:24:38 +00:00
Simon Brooke e5f40032e9 Now safely detecting (but not dealing with) integer overflow. 
Also printing and reading integers with comma separators.

Simon Brooke 02fe5669d8 Complete reworking of the REPL 
which is good in itself, but not what I was meant to be working on.

Simon Brooke 47f4b4c7f7 Bug was in integer_to_string; all tests now pass. 2018-12-30 12:07:38 +00:00
Simon Brooke 61573d85d9 /all-integers-are-bignums: broken, but I don't know why. 2018-12-30 11:10:14 +00:00
Simon Brooke 489f008044 Printing of bignums basically done, not tested. 2018-12-29 23:44:28 +00:00
Simon Brooke 342f0308d3 The beginning of bignums is in place, tests still pass. 2018-12-29 22:30:07 +00:00
Simon Brooke 75abfb4050 Much better debugging, but it still doesn't work 2018-12-27 21:37:38 +00:00
Simon Brooke 6ee9f9b59a Begun work on bignums; changed integer size to 64 bits 
I'm fairly sure the size of a long int on my machines is 64 bit anyway, but for portability it needs to be explicit.

Simon Brooke ad9b1cd7f8 Ratio arithmetic separated out into its own files. 2018-12-24 21:06:58 +00:00
Simon Brooke a5e1d3ccd8 Reorganised source files to make navigation easier 
All tests still pass (slightly to my surprise)
