## What is SmartCalculation_rjfv2?

Smart calculation: 
My App provides many unique calculations you can not find elsewhere. (see the 10 screenshots isubmitted). For example
 (1) Design a container with the minimum surface (for saving carton)     
 (2) Solution of an universal equation F(x)=0,
 ((3) Calculation of 2D to 8D arithmetical matrix,
(4) Maximum loading pattern.
 (5)Enter Date/Time to o btain time interval and decay calculation of radioactivity

Evolution to all traditional calculators! Calculation is done as soon as entering the mathematic expression. Greatly time saving!
6 consecutive auto-calculating fields are combined as a calculating matrix finishing a rather complicated calculation in 10 seconds instead of 2 minutes by other calculating tools.

It provides also all fundamental calculations for school, university, engineering, and scientific research, and offering some unique functions mentioned above:
General calculation :
   1.      +  -  x  / ,  power, root, exponent. 
   2.     Solutions of equation Ax² + Bx + C = 0: Enter coefficients A，B and C, the solutions are automatically calculated. 
   3.     Calculation of triangle: Enter lengths of side A and B, and angle A^B. The length of side C is automatically calculated.

Practical calculation :
   1.     Credit simulation: Enter amount, term and annual interest rate. The monthly installment is calculated.  Simulation of amortization in 2 terms is available.
   2.     Unique function for carton saving: Enter shape (box or cylinder), dimension and required number of the charge units (goods) to design a container with the minimum surface.
   3.     Unique function-Maximum loading pattern: Enter shape (box or cylinder), dimension of the charge units, and dimension of the pallet. Calculate the maximum number of charge units which can be loaded into the pallet. Show the maximum loading pattern.

Scientific calculation :
1.   Denary / natural logarithm, sine, cosine, tangent, arc sine/cosine/tangent, hyperbolic sine/cosine/tangent, compound function, calculation relevant to date-time such as decay of a radioactivity. 
2.   calculation of mathematical matrix (dimension 2 to 8),
3.   Chart of polynomial P(x) (max. order 8) and solution of equation P(x) = 0. 
4.   Chart of F(x) and solution of equation F(x) = 0. F(x) may be any basic function listed in (1) or compound of the basic mathematical functions.


## Version history (last 5 releases)

### 8.0 — 2026-04-30

The decimal point in a number is a comma ‘,’ in France instead of a point ‘.’ .
In the old version point ‘.’ is aways used in a number.
In the new version the decimal point is automatically adapted to a comma ‘,’ providing the app is installed in an iPhone or iPad distributed in France.

### 7.0 — 2026-03-19

Improve function of Max. loading (in【Practical】page):
Check weight limit when the user enters weight of the charge unit and charge limit of the pallet.  
If weight limit number less than the maximum loading number by volume calculation, weight limit number will be finally used.

### 6.0 — 2026-03-15

Button 【L】 (at top-right corner of 【General】page) is used to set Large/Small size of text font and all displayed elements. Click【L】-->【S】-->【L】.  The default status is always 【L】in version 5.0.  
In new version 6.0, the default status is【S】for devices with small screen sizes, or 【L】 for devices with large screen sizes

### 5.0 — 2026-03-04

The data of calculation can be saved and read out.

All the screenshots have been updated

### 4.0 — 2025-12-22

No release notes.
