+# Type Conversion Functions
+
+The following type conversion functions are provided by Sprig:
+
+- `atoi`: Convert a string to an integer
+- `float64`: Convert to a float64
+- `int`: Convert to an `int` at the system's width.
+- `int64`: Convert to an `int64`
+- `toString`: Convert to a string
+- `toStrings`: Convert a list, slice, or array to a list of strings.
+
+Only `atoi` requires that the input be a specific type. The others will attempt
+to convert from any type to the destination type. For example, `int64` can convert
+floats to ints, and it can also convert strings to ints.
+
+## toStrings
+
+Given a list-like collection, produce a slice of strings.
+
+```
+list 1 2 3 | toStrings
+```
+
+The above converts `1` to `"1"`, `2` to `"2"`, and so on, and then returns
+them as a list.
