When I compile it with the following line: g++ -o main.o -c -Werror -Wall -std=c++11 -fvisibility=hidden -fvisibility-inlines-hidden -DBOOST_SPIRIT_USE_PHOENIX_V3 -DUTEST -g main.cpp g++ -o main main.o -lboost_unit_test_framework
I get the following output: Running 1 test case...
*** No errors detected
If I lower the tolerance to 0.0004f then I'll get the following: Running 1 test case... main.cpp(8): fatal error in "TestCase": difference{0.00376352} between 45.00f{45} and 45.17f{45.1699982} exceeds 0.00039999999
*** 1 failure detected in test suite "Master test suite"
Why does it say that the difference is 0.00376352 and not 0.17....... ?
I suppose the output is a bit misleading. The difference printed (0.0037...) is approximately 0.17/45. In Christ, Steven Watanabe
