I am using PIC18F4620 to measure frequency. My frequency reading vary a lot -randomly , so I thought of rounding these values to nearest 100. How can I possibly do that in code ? Thanks

Im using C18 for PIC18F4620. Is there any inbuilt "rounding function" ?

Frequency Output:

13341

13379

13419

13326

13368

13408

13448

13357

13392

13427

Want to round it to nearest 100 :

13300

13300

13400...

Cheers

ps : Is it possible to round it to nearest 50 ?
