How to limit input formats in an edit text box?

In my GUI (programmatic one) there is an edittext box, used to enter coeeficients.
I need to check the format of input and allow only to these types:
5
0.5
1.6
5.9
0.4565132
5.0000
00000.5
Then I'll save them and call back.

STR2DOUBLE catches most of those things and outputs NaN if the number isn't valid. The only thing is that it will handle commas. I used REGEXPREP to switch any commas with asterisks so str2double can't process it.
validStr = {'5'
'0,5'
'1.0.6'
'5.9'
'0.4565132'
'5.0000'
'00000.5'};
validStr = regexprep(validStr,',','****');
str2double(validStr)

validStr = {'5'
'0.5'
'1.6'
'5.9'
'0.4565132'
'5.0000'
'00000.5'};
if any(strcmp(get(hEditBox,'String'),validStr))
%code
else
warndlg('Edit box string is not valid.')
end

Why not just use a popupmenu?
uicontrol('style','popupmenu','string',{'0.5','3.14','1.6'})
