"Numeric return value expected" when assigning array to a user-defined function that returns a string

[sokipdx]

I am trying to assign an element of an array to a user-defined function that returns a string, but I get an error when I run this code:



str_list = newArray(1); // strings
num_list = newArray(1); // numbers

str_list[0] = str_fx("TEST");
num_list[0] = num_fx(9);

function str_fx (string) {
        return string+"fx";
}

function num_fx (num) {
        return num*num;
}




I get the error:
Numeric return value expected in the following line:
str_list[0] = str_fx("TEST" <)>;

Oddly, the num_fx function that returns a number works when assigning to an array element.

God day Noname,

is this

//////////////////////////////
str_list = newArray(1); // strings
num_list = newArray(1); // numbers

str_list[0] = "" + str_fx("TEST");
print(str_list[0]);

num_list[0] = num_fx(9);
print(num_list[0]);

function str_fx (string) {
        string += "fx";
        return string;
}

function num_fx (num) {
        return num*num;
}

//////////////////////////////

what you wish to achieve?

Best

Herbie

Thank you Herbie, the empty string in the line below was the key part missing!

str_list[0] = "" + str_fx("TEST");
