Fomcal is a calculator to calculate quickly with formula inputted already. Since you can register formulas used in daily routine by yourself, there is no need to search or to develop the dedicated calc app. Moreover, Fomcal can be also available as a general function calculator pad (option). Registered formula can be utilized as a function in the other formula or on the calcpad. And constants or variables can be used in these. Fomcal can show descriptions and a figure, about formulas and variables. In addition to the numeric functions such as trigonometric functions, you can also use the logical or comparison functions. By describing separated multiple of a formula with a semicolon';', you will be able to calculate these at the same time. Temporary variables are available in formula definition as followings. exp) x=1;x+2 result) 3 You can try a parameter study with specifying an initial value, a incrementation and a repeat number. The result can be exported as CSV data. Following formulas are preset as samples. ・Hypotenuse of Right Triangle - Geometry ・Cross-sectional Performance of Rectangle - Mechanics of materials ・Roots of quadratic equation - Mathematics ・Compound interest calculation - Business ・Number of years to become N times with compound interest calculation After purchase of "Enhancements (former Restriction Release)" with In-App purchase, you will be able to following functions. ・Export/import of formula data. ・A special numeric pad will be utilized for efficient inputting. ・Function calculator pad. ・Parameter study. From Ver.3.3, "Extended Syntax" feature is available. With $IF, $FOR, $WHILE or etc., branch or iterative operation is easily specified.
