# `parseint` Function
|
|
|
|
`parseint` parses the given string as a representation of an integer in
|
|
the specified base and returns the resulting number. The base must be between 2
|
|
and 62 inclusive.
|
|
|
|
All bases use the arabic numerals 0 through 9 first. Bases between 11 and 36
|
|
inclusive use case-insensitive latin letters to represent higher unit values.
|
|
Bases 37 and higher use lowercase latin letters and then uppercase latin
|
|
letters.
|
|
|
|
If the given string contains any non-digit characters or digit characters that
|
|
are too large for the given base then `parseint` will produce an error.
|
|
|
|
## Examples

```

|
