In the first method you aren't doing an assignment, are sending the message
= to the temp isValid, if you change the method to:
decimalFromBinary: aString
| result isValid |
* isValid := self isValidBinary: aString.*
isValid
ifTrue: [ result := 0.

Hello,
I have to make some code that convert a binary to a decimal and im not
allowed to use the convert methods that Pharo has.
So I have written this :
decimalFromBinary: aString
| result isValid |
isValid = self isValidBinary: aString.
isValid
10 matches
