2013-04-23Added == operator to compare Numbers & stringsMike Buland
We may be able to go even a step further, but it actually parses the string as a number with the same radix and scale as the left hand side of the equation and then compares them as Numbers. This means that it's actually more resiliant to minor formatting differences.
2013-04-23Added stdlib for exit in the options.cpp file.Mike Buland
2013-04-23Added cli params & a unit test.Mike Buland
2013-04-22Just tweaked the starting banner.0.02Mike Buland
2013-04-22Fixed = bug in lexer (they halted it).Mike Buland
2013-04-22There is now a parser & calculator interface.Mike Buland
2013-04-22Fixed bug in multiply, added toInt32 function.Mike Buland
Multiply was ignoring the zero column, which was odd. I fixed this other places but apparently missed multiply.
2013-04-21FIxed fractional support in comparisons.Mike Buland
They still don't handle mixed scale comparisons correctly, it shouldn't be too hard to add, but yeah...not supported yet.
2013-04-21Corrected zero-length PackedIntArray bug.Mike Buland
If the array was zero elements long and then append was used it wouldn't allocate memory, but it would try to write to a pointer.
2013-04-19Added routines to get/set scale.Mike Buland
2013-04-19Corrected bugs in division scaling and string parsing.Mike Buland
2013-04-19Fractional divisoin works.Mike Buland
It doesn't round yet, and there's a chance I should be increasing the precision, right now it keeps the precision of the left hand side number.
2013-04-19It does fractional division, but the result is an int.Mike Buland
It's funny, I haven't extended division past the ones place yet, but it does work correctly, so in theory it won't be too hard to do. I may need a little bit of extra code in the PackedIntArray class to insert a new digit at the begining.
2013-04-17Division, attempt one - broken.Mike Buland
It doesn't work by any means, and I think I confused myself partway through. I shouldn't code when I'm that tired, at least not on something this complex.
2013-04-17Now you can multiply fractional numbers.Mike Buland
2013-04-17You can now add and subtract fractional numbers.Mike Buland
2013-04-17Fractional portions parse now.Mike Buland
2013-04-17Well, the fractional portion is...making...progress...Mike Buland
2013-04-16Broke the string parser.Mike Buland
2013-04-16Cleaned up some naming.0.01Mike Buland
iOrd is now iScale (places to the right of the decimal. And iOrder is now iIdx, since it was just an index.
2013-04-16Added formatter for Number.Mike Buland
I'm a little embarassed that I didn't do this from the start, made the code so much easier to read.
2013-04-16Full support for arbitrary radixes is in place.Mike Buland
It computes the radix and bitwidth dynamically, we could probably speed that up another step by simply having a table of common ones, but for now it'll work for anything.
2013-04-16The divide function is public now.Mike Buland
2013-04-16Added /, %, and = operators.Mike Buland
Division now works just fine, but by long division. There are apparently much faster ways of doing division, but as long as it works I feel like that's a great start :)
2013-04-16Added operators: -, ==, !=, <, >, <=, >=Mike Buland
Still working on division, needed some other operators to make it work.
2013-04-15Addition, subtraction, and multiplication work nowMike Buland
Division isn't working yet, there are too many options, I'll figure out something eventually :-P
2013-04-15Initial checkin.Mike Buland
This project will most likely just be stuck into libbu++, but I didn't want to deal with building it all in windows.
