xrb-prettify

DEPRECATED - Please use nano-prettify instead. Due to RaiBlocks rebranding to Nano this library is not longer supported.

Prettify / format RaiBlocks (XRB) Raw amounts to be more human-readable. Format amounts in any RaiBlocks compatible unit e.g. uxrb, Gxrb etc.... Adds decimal point and commas where necessary. Raw amounts are commonly returned when interacting with a RaiBlocks node (rai_node)

e.g. "2100176034320859259343606608761791" becomes "2,100.176034"

Install

npm install --save xrb-prettify

Include in scripts

// require
var xrbPrettify = require('xrb-prettify').xrbPrettify

// require (ES6 version)
const { xrbPrettify } = require('xrb-prettify')

// import
import xrbPrettify from 'xrbPrettify'

Usage Example

xrbPrettify("2100176034320859259343606608761791")
// "2,100.176034"

Note

xrb-prettify works with strings only. If you need to deal with numbers you can try converting returned results to a numeric format using parseInt or parseFloat where applicable.

API

xrbPrettify(raw, config <optional>)

Parameters

raw (number) - The Raw amount, returned when performing API calls to a RaiBlocks node (rai_node).

config (object) <optional> - Configuration for the returned result. The configurations are:

• unit (Possible values: 'raw', 'uxrb', 'mxrb', 'xrb', 'kxrb', 'Mxrb', 'Gxrb') - Specify which RaiBlocks unit is used to prettify the Raw amount. Default unit is 'Mxrb'.
• commas (boolean) - Choose whether or not to display commas where necessary e.g. "1,000,000.000000". Default: true
• decimals (boolean) - Choose whether or not to display decimal places. Default: true
• decimalPlaces (number) - Number of decimal places to display. Default is 6. Enter 0 to show all decimal places.

Examples

Prettify a Raw amount

xrbPrettify("2100176034320859259343606608761791")
// Result: "2,100.176034"

Prettify a Raw amount using the 'xrb' unit (overridiing the default unit 'Mxrb')

xrbPrettify("2100176034320859259343606608761791", { unit: 'xrb' })
// Result: "2,100,176,034.320859"

Prettify a Raw amount without commas

xrbPrettify("2100176034320859259343606608761791", { commas: false })
// Result: "2100.176034"

Prettify a Raw amount without decimal places

xrbPrettify("2100176034320859259343606608761791", { decimals: false })
// Result: "2,100"

Prettify a Raw amount with 10 decimal places (overridiing the default of 6 decimal places)

xrbPrettify("2100176034320859259343606608761791", { decimalPlaces: 10 })
// Result: "2,100.1760343208"

Prettify a Raw amount using a combination of configurations

xrbPrettify("2100176034320859259343606608761791", 
  {
    commas: false,
    decimals: true,
    unit: 'xrb',
    decimalPlaces: 10
  }
)
// Result: "2100176034.3208592593"
