Package Exports
- deci-mal
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (deci-mal) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
Deci-mal
Simple Decimal type for Javascript.
Simple Decimal type which allows for:
- conversion from numbers;
- conversion from strings;
- specification of precision;
- changing of precision;
- addition of Decimals;
- subtraction of Decimals;
- multiplication of Decimals;
- division of Decimals.
When doing add, sub, mult, div-operators with two Decimals, the result will have the precision of the source Decimal with the highest precision.
Deci-mal uses an integer for internal storage.

Example usage
var decimal = require('./');
var Decimal = decimal.decimal;
// conversion from numbers
var a = decimal.fromNumber(20, 2); // 20.00
var b = decimal.fromNumber(40.1, 4); // 40.1000
// conversion from strings
var c = decimal.fromString('60.60001', 2); // 60.60
// specification of precision
var d = new Decimal(1); // 0.0
// changing of precision
b.newPrecision(2).toString(); // 40.10
// addition
a.add(b).toString(); // 60.1000
// subtraction
a.sub(b).toString(); // -20.1000
// multiplication
a.mult(b).toString(); // 802.0000
// division
a.div(b).toString(); // 0.4988Unit testing
