Converts any big/small/precise decimal number represented as String, to exponential notation.
npm install to-exponentialConverts any arbitrarily big, small, or precise number represented as a String,
to exponential notation. For regular numbers it works just like JavaScript'sNumber.toExponential().
The returned String can be used as a unique identifier for the number's value.
It accepts any decimal number represented as a String.
- It converts it to exponential notation without loss of precision.
- It works for high precision numbers, also for those that do not fit in a
64-bit JavaScript Number variable.
(They still have to fit in Strings, which have some maximum length).
- It works for very large and very small numbers, also for those with an
exponent (e...) that does not fit in a 64-bit JS number.
The exponent always gets a sign (+ or -), consistent with the output ofNumber.toExponential(). So e.g. 5 becomes '5e+0' (not '5e0').
Returns false if the String does not represent a valid decimal number.

const toExponential = require('to-exponential');
console.dir( toExponential('0.5') ); // => '5e-1'.

console.dir( toExponential('10.5') ); // Outputs '1.05e+1'.
console.dir( toExponential('0.105e2') ); // Outputs '1.05e+1' too.
