## genAuthSig(apiSecret, payload) ⇒ <code>Object</code>
Generates an auth signature, payload, and nonce for passing to the WS & REST
APIs

**Kind**: global function  
**Returns**: <code>Object</code> - authSignature  

| Param | Type | Description |
| --- | --- | --- |
| apiSecret | <code>string</code> |  |
| payload | <code>string</code> | optional signature payload, generated by default |

<a name="isClass"></a>

## isClass(f) ⇒ <code>boolean</code>
**Kind**: global function  
**Returns**: <code>boolean</code> - isClass  

| Param | Type |
| --- | --- |
| f | <code>Class</code> | 

<a name="isSnapshot"></a>

## isSnapshot(msg) ⇒ <code>boolean</code>
**Kind**: global function  
**Returns**: <code>boolean</code> - isSnapshot  

| Param | Type |
| --- | --- |
| msg | <code>Array</code> \| <code>Array.&lt;Array&gt;</code> | 

<a name="nonce"></a>

## nonce() ⇒ <code>number</code>
Generates a new nonce for usage with the Bitfinex APIs

**Kind**: global function  
**Returns**: <code>number</code> - nonce  
<a name="padCandles"></a>

## padCandles(candles, candleWidth) ⇒ <code>Array.&lt;Array&gt;</code>
Fills in missing (0 volume) candles on the provided dataset. The result is a
new array (does not mutate)

**Kind**: global function  
**Returns**: <code>Array.&lt;Array&gt;</code> - paddedCandles  

| Param | Type | Description |
| --- | --- | --- |

<a name="setSigFig"></a>

## setSigFig(n, maxSigs) ⇒ <code>string</code>
Smartly set the precision (decimal) on a value based off of the significant
digit maximum. For example, calling with 3.34 when the max sig figs allowed
is 5 would return '3.3400', the representation number of decimals IF they
weren't zeros.

**Kind**: global function  
**Returns**: <code>string</code> - str  

| Param | Type | Description |
| --- | --- | --- |
| n | <code>number</code> |  |
| maxSigs | <code>number</code> | default 5 |

<a name="setPrecision"></a>

## setPrecision(number, decimals) ⇒ <code>string</code>
Casts the provided value to a number if required, and limits the number of
decimals to the specified value. Returns a decimal string.

**Kind**: global function  
**Returns**: <code>string</code> - result  

| Param | Type | Default |
| --- | --- | --- |
| number | <code>number</code> \| <code>string</code> | <code>0</code> | 
| decimals | <code>number</code> | <code>0</code> | 

<a name="prepareAmount"></a>

## prepareAmount(amount) ⇒ <code>string</code>
Prepares a amount for submitting via the API

**Kind**: global function  
**Returns**: <code>string</code> - preparedAmount  

| Param | Type | Default |
| --- | --- | --- |
| amount | <code>number</code> \| <code>string</code> | <code>0</code> | 

<a name="preparePrice"></a>

## preparePrice(price) ⇒ <code>string</code>
Prepares a price for submitting via the API

**Kind**: global function  
**Returns**: <code>string</code> - preparedPrice  

| Param | Type | Default |
| --- | --- | --- |
| price | <code>number</code> \| <code>string</code> | <code>0</code> |
