R.calc is an electronic calculator withafunction of “Normal Calculator” and the function of“ReverseCalculator”.

Function in a “Normal Calculator”:
- You can calculate including "Square root calculation"and"Exponentiation calculation" in the middle of a seriesofcalculations.
- You can save the value of the electronic calculator.
Three sp1&sp2&sp3 buttons can save the value oftheelectronic calculator.
And you can paste the value that you saved when itisnecessary.
Value that you saved is not lost when you turn offyoursmartphone.
And values that have been saved can be used in common with"ReverseCalculator".
- You can perform the correction of the input value with anarrowbutton or a tap.

A basic function of "Reverse Calculator" is a calculation bythecalculating formula:
- Reverse calculation function
For example, you can be calculated, such as in thefollowingexample.
The calculation of the BMI (degree of corpulence)is“Weight÷（Height÷100）÷（Height÷100）”, but can write itas“Weight÷（Height÷100）＾2”. (Weight is kg , Height is cm)
Specifically, 75kg÷（170cm÷100）＾2 will be the BMI =25.9515571.
If you want to know the weight of the case of 24 BMI, dothefollowing.
Rewrite “75” to “?”, 75÷（170÷100）＾2 → ?÷（170÷100）＾2.
And “RUN” button, Answer ?=69.36, Body weight is 69.36kg.
- You can save a formula frequently used.
You name a calculating formula and can save it. (Or omitthename)
In addition, you save it with the number of the calculatingformulaas a memo and when you use it, you rewrite a memo to anumber andcan calculate.
Example: 75÷（170÷100）＾2＝BMI → Weight÷（Height÷100）＾2＝BMI
Value that you saved is not lost when you turn offyoursmartphone.
- Calculation log is saved RUN button is pressed.
You can re-calculated using the calculation log.
- The button of sp1&sp2&sp3 is shared with“Normalcalculator”.
