Download Custom Formulas v3.3 [Paid]
Requirements: Android 4.0 and up | Size: 4,6 MB
This powerful app lets you create your own custom formulas and then perform computations using them by prompting you for the input values. This app is easy to use, but unlike simpler apps, multiple entered values can be fed into multiple formulas and multiple output values can be displayed. The output of one formula in a group can be fed into the next by using the same variable name. Related formulas can be grouped into categories to make them easy to find. e.g. Maths formulas, Surveying formulas, Loan interest formulas etc. The order of variables displayed to the user can be changed, as can the number of decimal digits of precision shown in the output fields. Three example formulas are pre-installed with the app. In order of increasing complexity they are: slope percentage, compound interest, and point scale factor. A formula group can be exported to a text file. Other users of the app can then import it, allowing your creations to be shared. Note: Do not use “e” or “pi” as variable names since these are pre-defined constants. This app uses the JFEP library. See the following page for the list of supported functions:
(Plus int, round, ceil, and floor have also recently been added). Whats new:
Fixed two bugs: · If the input variables for one formula were being used in other formulas, the results of the computation of the other formulas were incorrect.
· When the last formula group in a category was deleted, previously its formulas were still remaining visible on the main page.
