Setting odd/even numbers and decimal places in ENVI widgets [message #65625]

I'm currently using widget_slider (and widget_sslider), but I need to
constrain them to only odd numbers (so I can set the kernel size for
processing later in my User Function). How does one make sure that
such widgets only return (and display) either odd or even numbers?

In a similar fashion I'm using cw_fslider and need to return numbers
with just one or two decimal places. How can I make sure the widget
only displays (and returns) numbers with such few decimal places?
