Kalkyl Pro is still free and available for every one of you! Fixes a bug in the display (not calculation) of repeated decimals of rationals of a certain rare format.

With this release Kalkyl Pro is made free and available for every one of you! New features include: • Unit conversions with complex units – from EUR/m² to USD/ft² or m/s to mi/h with up-to-date currencies • Collaborative Documents – allowing nested and dependent expressions and sharing with friends • Symbolical Differentiation – when you just can't remember what d/dx of √cos (x²) is • … last but probably the least: The Light app icon

Fixes a rare issue where fractions with special properties could result in repeated decimals being presented with the wrong first or last digit
