<p><!-- the 'p' starts a paragraph of normal text --> numedit is a simple edit control which forces the user to enter a double value in e
notation, such as 1.23, 12e4, -12e4, etc. the member functions getvalue() and setvalue()
make working with doubles in the edit field a bit easier. </p>
<p>just declare a variable as type cnumedit, and off you go. <!-- create more blocks of article text as needed --> <!-- create more blocks of source code as needed --> <!-- demo project --> </p>
