+  - Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal
   - 5 KB minified and gzipped
   - Simple API but full-featured
   - Works with numbers with or without fraction digits in bases from 2 to 36 inclusive
-  - Replicates the `toExponential`, `toFixed`, `toPrecision` and `toString` methods of Javascript's Number type
