$3
Format the given value in bytes into a string.
将给定的字节值格式化为字符串。
Arguments
| Name | Type | Description |
| ------- | ------------------ | ----------------------------------------------- |
| data | number｜bigint | Number value to format. 要格式化的数值 |object
| options | | Conversion options for format. 格式化的选项。 |
Options
| Property | Type | Description |
| ------------- | --------------------- | ------------------------------------------------------------------------------------------------------------------------ |
| decimal | number｜undefined | Maximum number of decimal places to include in output. Default: 2. 输出中包含的最大小数位数。默认值：2。 |kilobinary
| standard | ｜kilo | base. kilobinary = 2^10 ; kilo = 10^3. Default: kilobinary. 进制规范。千位二进制=2^10；千位=10^3。默认值：kilobinary |string
| unitSeparator | ｜undefined | Separator to use between number and unit. Default: ' '. 用于数字和单位之间的分隔符。默认值：' ' |
Returns
| Name | Type | Description |
| ------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| results | string | Return string. For non number or bigint, as well as cases less than 0, exceptions are thrown. 返回 string。对于非 number 或 bigint，以及小于 0 的情况，均抛出异常。 |
$3
Parse the string value into an integer in bytes. If no unit is given, it is assumed the value is in bytes.
将字符串值解析为以字节为单位的整数。如果没有给出单位，则假定该值以字节为单位。
Arguments
| Name | Type | Description |
| ------- | -------- | --------------------------------------- |
| data | string | String value to parse. 要解析的字符串。 |object
| options | | Parsed options. 解析的选项。 |
Options
| Property | Type | Description |
| --------------- | ---------------------- | ------------------------------------------------------------------------------------------------------------------------ |
| forceKilobinary | boolean｜undefined | If true, consider kilo as kilobinary, i.e. using 2^10 base. 如果为真，则将千位进制视为千位二进制，即使用 2^10 进制换算。 |
Returns
| Name | Type | Description |
| ------- | -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------ |
| results | number｜bigint｜null | Returns null on error. Otherwise, return the value of number or bigint in bytes. 出错时返回 null。否则以字节为单位返回 number 或 bigint 的数值。 |
