You're assuming this wasn't intentional. As the division by 1000000
ends up losing the fractional rate, I decided to leave 1-4MHz as kHz,
so something like 1.832MHz would be displayed as 1832kHz and not
1MHz.

Thanks for clarification of this. Now, it is better for me to understand this piece of code. Best Regards, Bo Shen
