/**
 * https://github.com/inkle/ink/blob/master/Documentation/ink_JSON_runtime_format.md#native-functions
 *
 * These are mathematical and logical functions that pop 1 or 2 arguments from the evaluation stack, evaluate the result, and push the result back onto the evaluation stack. The following operators are supported:
 *
 * "+", "-", "/", "*", "%" (mod), "_" (unary negate), "==", ">", "<", ">=", "<=", "!=", "!" (unary 'not'), "&&", "||", "MIN", "MAX"
 *
 * Booleans are supported only in the C-style - i.e. as integers where non-zero is treated as "true" and zero as "false". The true result of a boolean operation is pushed to the evaluation stack as 1.
