Kalkulilo is a comfortable calculator program and offers several different modes. - The scientific mode offers all the usual functions and operations like the basic arithmetical operations, power, logarithm, roots, trigonometry etc. - The bit/integer mode offers logical operations (AND, OR, XOR, >>, etc.) on bit level. All values can be displayed as binary, octal, decimal or hexadecimal numbers. Calculations can be done in 8, 16 32 or 64 bits. - In the statistics mode you can create a sample by adding several values and then calculate mean, median, quantil values, variance, standard deviation, range etc. - Trigonometry mode provides lots of trigonometric functions, including legacy ones - The base/radix mode allows you to do calculations with numbers of base 2 to base 36 - The Time mode lets you directly work with time values (hours, minutes seconds) - A simple calculator is also included, with just the basic operators and large buttons. The user interface can be customized, you can change the key colors for different categories of functions and operators which helps to distinguish and find these more easily. The App also includes calculator widgets for the homescreen which allows to do calculations directly from your homescreen and a calculator for the Apple Watch.
