number-format-analyzer
Analyzes a list of numbers to be able to output them formatted as a list as good as possible aligned at the decimal separator
Usage
import numberListAnalyzer from 'numberListAnalyzer';
const numbers: number[] = [
1,
1.5
12,
1.567,
3.1462e-5
]
const numberFormatConfig = numberListAnalyzer(numbers)
console.log(numberFormatConfig.integerLength)
console.log(numberFormatConfig.fractionalLength)
console.log(numberFormatConfig.totalLength)
->
2 // two digit of 12
9 // 4 fractional digits and the exponent of -5
12 // all digits and the decimal separator
The values could be used to output the numbers like that:
1
1.5
12
1.567
0.000031462
The totalLength
allows the user to change the fractionalLength
and the integerLength
in the
postprocessing. The totalLength
would return the
changed value. This could be user to limit the number of fractional digit to specific maximum.
You could change the fractionalLength
of the above
example to limit the fractionalLength
to 5 digist.
The totalLength
would change to 7
numberFormatConfig.fractionalLength = Math.min(numberFormatConfig.fractionalLength, 5);
console.log(numberFormatConfig.totalLength);
->
7
