Would it be possible to add a flag in String::getFloatValue and other string to value conversion a flag to know if the conversion was a success ?
In our own String class at UVI we have this
float String::toFloat(bool *pOk = nullptr)
and it would be great to have someting similar in Juce
It is backward compatible with the current code and you can add a pointer to a bool if you want to check for potential error.
