Casting

To number

Input	An argument of any type.
Output	The argument converted to a number.

Signature

to_number(a: Any): Number

Example

to_number("42") // returns 42

To integer

Input	An argument of any type.
Output	The argument converted to an integer.

Signature

to_integer(a: Any): Number

Example

to_integer(3.7) // returns 3

To decimal

Input	An argument of any type.
Output	The argument converted to a decimal number.

Signature

to_decimal(a: Any): Number
