8e31f5d869 Revised internal type naming scheme to better sandbox Unity away from everything else. Sure, short was nice, but not at the expense of naming collisions. 2016-11-29 08:38:51 -05:00

aa4d773df2 Tests for Printing All float values 
Takes about 10 minutes to run all floats, so split into 3 tests for parallel
running later. This was useful during development for finding hard corner cases
and getting the routine to high quality. Off by default.
Note that all floats 16.0 and up can be represented uniquely (in this format) and will
round-trip back to the exact same float with sscanf(). This property is true for
UnityPrintFloat, despite a few rounding error cases, it will produce output identity.

Better comments and refactor on round ties to even
Add upper threshold value on round to even feature since numerical precision issues
start to give approximations when dividing one large double by another. When tested
on float values, using 1e22 gave the fewest rounding errors.

Fix warnings from gcc. Some float constants do not behave well in existing tests.
Add casts where conversions could be imprecise.

9653fbf7ac Use an integer cast to print floating point numbers more precisely 
Improve printing six decimal places, remove trailing 0's, fix the carry when
numbers like 0.9999999 round up and print leading zeros in the decimal

The first attempt at printing floats had precision issues where the last few
digits would often be wrong. This next approach may yield a better algorithm
for numbers less than 4.29 billion, those that fit in 32 bits.

ac455f2798 We can’t guarantee that the built-in function insane will return 1. It might return any other non-negative value. Therefore we need to force it to be 1 so we can use the comparison operator later. 2016-11-15 09:29:08 -05:00

dce6d329ff Finished fixing floating point comparisons. We have streamlined how floats and doubles are checked, but we still can't compare them for equality directly. So we're directly testing for infinite and NaN before checking diffs. Also, we've officially decided that for testing purposes NaN shall equal NaN, +Inf shall equal +Inf, and -Inf shall equal -Inf. It's what most people expect during a test. 2016-09-22 08:35:22 -04:00

593a03462e Add an option to omit UNITY_OUTPUT_CHAR declaration from the header 
This solves the warnings from -Wredundant-decls when overriding the
  OUTPUT function with a function declared in another header.
 It's better this is the non-default option, since using it requires either
  a declaration of the new function OR a preprocessor guard on declaring
  UNITY_OUTPUT_CHAR (as in unity.c here), in every file using the function.
 See Pull Request #185 for more.

573481729b Revert commits 720ea42 and a27b03c which broke the Fixture build 
These were aimed at preventing the internals header from declaring
  a prototype for 'int UNITY_OUTPUT_CHAR(int);'. The second part fixed
  an omitted declaration in the tests caused by the first commit.
 Will replace the default behavior & add an option for this in next commit
