--- title: int linktitle: int description: Creates an `int` from the argument passed into the function. godocref: date: 2017-02-01 publishdate: 2017-02-01 lastmod: 2017-02-01 categories: [functions] menu: docs: parent: "functions" keywords: [strings,integers] signature: ["int INPUT"] workson: [] hugoversion: relatedfuncs: [] deprecated: false aliases: [] --- 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. {{% /note %}}
