Free angular software for mac

GCMathParser is a free class that you can use in applications that need a way to deal with mathematical expressions input by the user.
GCMathParser accepts an NSString consisting of a well-formed mathematical expression, evaluates it, and returns the result. It supports arbitrary named variables, so it is also perfect for graph plotting applications.
Supported functions and operators:
- Basic operators: +, -, * (multiply) and / (divide)
- Mod operator: %
- Exponentiation operator: ^
- Negation: unary -
- Assignment: =
- Log functions: log(), log2(), ln(), exp()
- Transcendental functions: sin(), cos(), tan(), asin(), acos(), atan(), sinh(), cosh(), tanh(), asinh(), acosh(), atanh()
- Square root function: sqrt()
- Rounding functions: ceil(), floor(), round(), trunc(), rint(), near()
- Angular conversion functions: dtor(), rtod()
- Absolute value function: abs()
- Constants: pi

System requirements:
- Xcode

JJIKANKI is interesting tool because the word JIKANKEI is the Time System in Japanese.
JIKANKEI does not express scientific accurate data. It is just an Art work. Linger in the morning brightness, in the afternoon glow, and enjoy the gradually changing seasons on this globe. The author makes no warranties to your physical and/or mental damages.
JIKANKEI displays angles of the SUN and local times of cities and places on the Earth. Sunrise and sunset data are taken from US Naval Observatory Date Services through Internet.
The latest version shows Sun directions and FUJYO JIHOU (gradually changing time) that is before Westernized Japanese Clock System. FUJYO JIHOU divides daytime to six equal periods which an angular unit to 30 degrees is measured along the celestial equator.
When it is equinox one of periods is almost two hours. However It is changed by seasons, summer time is longer and winter time is shorter. The each divided points were named to the 6 directions of zodiac symbols in day time and the 6 directions of symbols in evening, such as U (rabbit, sunrise: six gongs), TATSU (dragon, about two hours form sunrise: five gongs), MI (snake, about four hours from sunrise: four gongs), and so on.
JIKANKEI also shows one twelfth of daytime and one twelfth of evening time for the understanding of differences between twenty fourth even divided modern clock system.
Enhancements:
- Added: Time signal of SUN Music.
- Fixed: When JIKANKEI was started up, a default place name did not show correctly.
