## Significant Figures

A Java number class for figuring out how many significant figures each of the numbers in a calculation has and displaying the result appropriately.

### Example

Multiplying numbers using significant figures.

```// Numbers to multiply
String[] args = {"1.0", "2.0"};
SignificantFigures number;
int sigs = Integer.MAX_VALUE;
double result = 1D;
for (int i = 0; i < args.length; i++){
// For each number, figure out significant figures
// and multiply the numbers
number = new SignificantFigures(args[i]);
sigs = Math.min(sigs, number.getNumberSignificantFigures());
result *= number.doubleValue();
}
// format and display the result
number = new SignificantFigures(result);
number.setNumberSignificantFigures(sigs);
System.out.println(number);
```

### Example

```// Numbers to add
String[] args = {"1.0", "2.0"};
SignificantFigures number;
int lsd = Integer.MIN_VALUE;
int msd = Integer.MIN_VALUE;
double result = 0D;
for (int i = 0; i < args.length; i++){
// for each number figure most and least
// significant digit then add the number.
number = new SignificantFigures(args[i]);
lsd = Math.max(lsd, number.getLSD());
msd = Math.max(msd, number.getMSD());
result += number.doubleValue();
}
// format and display the result
number = new SignificantFigures(result);
number.setLMSD(lsd, msd);
System.out.println(number);
```
