Store description excerpt
The Bristol Calculator provides a platform for both simple and more technical calculations involving vectors, matrices and complex numbers. Separate input and output screens with touch cursor control facilitates editing and checking. Option settings provide control over the output and input screen presentation. Keys can be personalised for often used functions and variable names. Data entry is also possible from the hardware keyboard as well as the calculator's screen keypad. Help pages provide built in contextual help. Work can be saved and templates created for future calculations. Vectors, matrices and complex numbers are handled by the same basic function operators used for numbers; the context determining operation. As well as standard mathematical functions, bespoke routines for sums, products, matrix inversion, numerical integration and solving transcendental equations are included. User functions can also be created. Table and graph plot functions display results. The free version of the Bristol calculator allows two files to be stored. A modest one-off In-App purchase unlocks this restriction. Otherwise, the free version is fully functional. This is a standalone application and there are no links to advertisers or third party software.
