Programming code enhancements for IOS13 Added data input and output in radians, degrees/minutes/seconds Added angle converter between decimal degrees, radians, and degrees/minutes/seconds Updated interface.

Programming code enhancements for IOS13 Added data input and output in radians, degrees/minutes/seconds Added angle converter between decimal degrees, radians, and degrees/minutes/seconds Updated interface.

Added the ability to calculate triangles using Area as an input, as well as displaying Area when triangles are calculated from other known values. Localisation support for Chinese language.

UI updated for IOS7. Revised input method replacing the ATM style data entry with a conventional number pad. Increased the size of numbers that can be calculated to 15 significant figures. Added a settings page where users can set the number of decimal places to calculate for lengths and angles. Removed Tabbar and replaced with side menu

Added a new tab to calculate missing values of regular polygons. Regular Polygons are shapes in which all the sides and all the internal and external angles are equal. Triangles,Squares,Pentagons,Hexagons,Heptagons,Octagons, Nonogons,Decagons,Undecagons,Dodecagons,Tridecagons and Tetradecagons can be solved by entering one known value of Side length, Perimeter, Area, Circumcircle Diameter or Innercircle Diameter.

Added a Chord calculator to evaluate circle segments given two known values. The calculator has Chord, Arc Length, Included Angle, Sagitta, Apothem and Radius. By entering any two values, the remaining values are calculated using a combination of trigonometry and calculus. This version also enhances the functionality of the Regular and Irregular triangle calculators, by increasing the values of known elements that can be entered to solve triangles. The old version was restricted to values of 500mm, but the new version now allows values up to 999,999.999mm to be entered to solve the missing elements.
