Number 7 is a small program written on java which can help you a lot when you are working with formulas. It is completely open source.
It substitutes values in formulas, also it can automatically convert input parameters from a unit to another. So you don't even have to convert them.
- Homework
- Not only homework
First : Add a unit
Click on the Units button and then add a unit
Tip:
| Unit | Range/S.I. | Relation |
|---|---|---|
| Name of the unit | e.g. The range for kM is M. For dL is L. | For cM the relation is 100. For dL R. is 0.1. |
The relation for a new Range/S.I. is always 1. To get the relation for another value you just have to convert the Range/S.I. value into what you want. For example 1 M is 100 cm. And 1 M is 0.001 kM.
Second : Add a formula
This is pretty straightforward, just add your formula. The name should only include letters, numbers and spaces. The formula should be supported by exp4j. List of all supported words:
- abs: absolute value
- acos: arc cosine
- asin: arc sine
- atan: arc tangent
- cbrt: cubic root
- ceil: nearest upper integer
- cos: cosine
- cosh: hyperbolic cosine
- exp: euler's number raised to the power (e^x)
- floor: nearest lower integer
- log: logarithmus naturalis (base e)
- log10: logarithm (base 10)
- log2: logarithm (base 2)
- sin: sine
- sinh: hyperbolic sine
- sqrt: square root
- tan: tangent
- tanh: hyperbolic tangent
- signum: signum function Also it supports the scientific notation. e.g. 1.0e-32. The powers work like this 8^2
Third : Enjoy!
The rest is pretty straightforward
