# Documentation: std.isbpl
|
|
|
|
The standard library. Everything here is (supposed to be) loaded before ANY other code is executed. It is responsible for things ranging from array literals and comments,
|
|
over type definitions, to string processing.
|
|
|
|
## Functions
|
|
|
|
### `ftos ::: float -> string`
|
|
|
|
[Unfinished]
|
|
Converts float to string
|
|
|
|
|
|
### `dtos ::: double -> string`
|
|
|
|
[Unfinished]
|
|
Converts double to string
|
|
|
|
|
|
### `stof ::: string -> float`
|
|
|

|
### `strsplit ::: string separator -> array`

### `inc ::: integer -> `

The integer argument is discarded as it is not useful.
|
|
|
|
|
|
### `dec ::: integer -> `
|
|
|
|
Uses _last_words to find the variable of the integer variable mentioned previously,
