But when I write floating number like 4.5 into field text, then write error...

I have tested my code:
set(handles.edit1,'String',num2str(4.5));
It's correct.

Here is on maybe better solution: use *find* function.
For example if you have string like this:
>>string = '453,45434';
you can use *find* function you have to check if there in string exist comma: find(string==',') the result will be 4.
Now, if you have string like this: >>string = '4534434' (without comma) the result for _find(string==',')_ will be Empty matrix: 1-by-0. I hope my advice will be helpful
