Additional contributions include converting code to use qDegreesToRadians() more widely and be consistent about the value of pi, using M_PI in C++ and Math.PI in JavaScript. The user also converted uses of QTime as a timer to QElapsedTimer and fixed deprecation warnings.
qt/qttools
Jan 2017 - Apr 2022
Qt Tools
Role in this project:Full-stack Developer
Full-stack DeveloperContributions:31 commits in 5 years 4 months
