How can I convert text to "number"?

MIT App Inventor Help

But it works, isn't it?
What did not work for you?

I have used this method in my app and have never faced any issues

2 weeks ago I and a few classmates tried using a string directly as a number. And it gave me an error message.

10

Could you show the error?

11

I want to

Label7(text) →  number

How can I ?

12

I don't exactly remember, neither do I have any screenshots

13

Is there any specific reason to covert it to number? Because as I showed, all operations work good with a text string containing only numbers

14

text "17" → number "17"

How ????

So where is the problem and what is the goal?

If you must:

but as previously said, the string will be treated as a number in mathematical operations. However, the number may be treated differently in (online databases) - e.g. firebase/mySQL/sqLite - but this will depend on how you transfer it.

@mal_ju never mentioned comparing of the spelling and numeral of any number!
@Salman_Dev kindly do not go off topic

Unlike lower level languages, AI2 has Duck Typing for math operations.

Thank you! This helped me. I was scared that numbers in text strings will be treated like in Small Basic, which means that "100" + "55" = "10055".
