Functions
- encodeName(name) ⇒
string.<uint64> Encode a name (a base32 string) to a number.
For performance reasons, the blockchain uses the numerical encoding of strings for very common types like account names.
- decodeName(value) ⇒
string - DecimalString() ⇒
string Normalize and validate decimal string (potentially large values). Should avoid internationalization issues if possible but will be safe and throw an error for an invalid number.
Normalization removes extra zeros or decimal.
- DecimalPad(value, precision) ⇒
string Ensure a fixed number of decimal places. Safe for large numbers.
- DecimalImply()
Ensures proper trailing zeros then removes decimal place.
- DecimalUnimply(value, precision) ⇒
number Put the decimal place back in its position and return the normalized number string (with any unnecessary zeros or an unnecessary decimal removed).
encodeName(name) ⇒ string.<uint64>
Encode a name (a base32 string) to a number.
For performance reasons, the blockchain uses the numerical encoding of strings for very common types like account names.
Kind: global function
Returns: string.<uint64> - - compressed string (from name arg). A string is
always used because a number could exceed JavaScript's 52 bit limit.
See: types.hpp string_to_name
| Param | Type | Description |
|---|---|---|
| name | string |
A string to encode, up to 12 characters long. |
decodeName(value) ⇒ string
Kind: global function
| Param | Type | Description |
|---|---|---|
| value | Long | String | number |
uint64 |
DecimalString() ⇒ string
Normalize and validate decimal string (potentially large values). Should avoid internationalization issues if possible but will be safe and throw an error for an invalid number.
Normalization removes extra zeros or decimal.
Kind: global function
Returns: string - value
DecimalPad(value, precision) ⇒ string
Ensure a fixed number of decimal places. Safe for large numbers.
Kind: global function
Returns: string - decimal part is added and zero padded to match precision
See: ./format.test.js
| Param | Type | Description |
|---|---|---|
| value | number | string | object.toString |
|
| precision | number |
number of decimal places |
Example
DecimalPad(10.2, 3) === '10.200'
DecimalImply()
Ensures proper trailing zeros then removes decimal place.
DecimalUnimply(value, precision) ⇒ number
Put the decimal place back in its position and return the normalized number string (with any unnecessary zeros or an unnecessary decimal removed).
Kind: global function
Returns: number - 1.0000
| Param | Type | Description |
|---|---|---|
| value | string | number | value.toString |
10000 |
| precision | number |
