Number

The return type is expected to be a floating-point number. Arcade will convert the return type to a float64 via the following transformations:

• booleans return 1 if true, 0 otherwise.

• integral types are converted to float64. This may be a narrowing conversion.

• float64 values are returned unchanged.

• null is converted to 0.

• strings are parsed as float64.

• all other types are converted to NaN.
