#### Simple byte size formatting.
|
||
|
|
|
||
|
|
This package implements types that can be used in stdlib formatting functions
|
||
|
|
like `fmt.Printf` to control the output of the expected printed string.
|
||
|
|
|
||
|
|
Floating point flags `%f` and %g print the value in using the correct unit
|
||
|
|
suffix. Decimal units are default, `#` switches to binary units. If a value is
|
||
|
|
best represented as full bytes, integer bytes are printed instead.
|
||
|
|
|
||
|
|
##### Examples:
|
||
|
|
|
||
|
|
```
|
||
|
|
fmt.Printf("%.2f", 123 * B) => "123B"
|
||
|
|
fmt.Printf("%.2f", 1234 * B) => "1.23kB"
|
||
|
|
fmt.Printf("%g", 1200 * B) => "1.2kB"
|
||
|
|
fmt.Printf("%#g", 1024 * B) => "1KiB"
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
Integer flag `%d` always prints the value in bytes. `#` flag adds an unit prefix.
|
||
|
|
|
||
|
|
##### Examples:
|
||
|
|
|
||
|
|
```
|
||
|
|
fmt.Printf("%d", 1234 * B) => "1234"
|
||
|
|
fmt.Printf("%#d", 1234 * B) => "1234B"
|
||
|
|
```
|
||
|
|
|
||
|
|
`%v` is equal to `%g`
