It is not for printing but for testing. I want to assert that a certain calculation gives the expected result.
Then you should use #assert:closeTo: and friends. (9.1 + (-2.0)) closeTo: 7.1 precision: 0.1.
I remembered about it, and implemented my own #assertDifferential:equals: which I first did convert to ScaledDecimals and then compares with #roundedByScale.
Floats should always be compared using an epsilon (precision) value in tests, not using equality.
Sure, but 7.1 roundTo: 0.1 should return 7.1. Shouldn't it? Regards! Esteban A. Maringolo
