Useful for turning strings into numbers.
|
|
|
|
```
|
|
{{ int "123" }} → 123
|
|
```
|
|
|
|
{{% note "Usage Note" %}}
|
|
If the input string is supposed to represent a decimal number, and if it has
|
|
leading 0's, then those 0's will have to be removed before passing the string
|
|
to the `int` function, else that string will be tried to be parsed as an octal
|
|
number representation.
|
|
|
|
The [`strings.TrimLeft` function](/functions/strings.trimleft/) can be used for
|
|
this purpose.
|
|
|
|
```
|
|
{{ int ("0987" | strings.TrimLeft "0") }}
|
|
{{ int ("00987" | strings.TrimLeft "0") }}
|
|
```
|
|
|
|
**Explanation**
|
|
|
|
The `int` function eventually calls the `ParseInt` function from the Go library
|
|
`strconv`.
|
|
|
|
From its [documentation](https://golang.org/pkg/strconv/#ParseInt):
|
|
|
|
> the base is implied by the string's prefix: base 16 for "0x", base 8 for "0",
|
|
> and base 10 otherwise.
