Functions: Type

Kahuna provides functions to check the type of a variable and to cast values between supported types, helping developers write safer and more predictable logic.

Type Checking Functions

Function	Description	Example
`is_null(x)`	Returns `true` if `x` is `null`	`is_null(null)` → `true`
`is_bool(x)`	Returns `true` if `x` is a boolean	`is_bool(true)` → `true`
`is_int(x)`	Returns `true` if `x` is an integer	`is_int(42)` → `true`
`is_double(x)`	Returns `true` if `x` is an double	`is_double(42.5)` → `true`
`is_string(x)`	Returns `true` if `x` is a string	`is_string("hello")` → `true`
`is_bytes(x)`	Returns `true` if `x` is a byte stream	`is_bytes(some_bytes)` → `true`
`is_array(x)`	Returns `true` if `x` is an array	`is_array([1, 2, 3])` → `true`

Type Casting Functions

Function	Description	Example
`to_bool(x)`	Casts `x` to a boolean	`to_bool("true")` → `true`
`to_int(x)`	Casts `x` to a int number	`to_int("42")` → `42`
`to_double(x)`	Casts `x` to a double	`to_float("42.5")` → `42.5`
`to_string(x)`	Converts `x` to a string	`to_string(99)` → `"99"`
`to_bytes(x)`	Converts `x` to a byte stream	`to_bytes("99")` → `[57, 57]`
`to_array(x)`	Casts a value to an array (if possible)	`to_array("a,b,c")` → `["a","b","c"]`

These functions are especially useful in dynamic scripting scenarios, when working with user input, or reading heterogeneous data from the key/value store.
