Question

I’m looking for a QT function to round a variable (integer) of type qint64 to the nearest ten.

For example:
1013 would round to 1010.
1019 would round to 1020

QT Assistant doesn’t seem to list any built in functions that would do this, but I could be looking in the wrong spot.

Any help would be appreciated.

Thanks,
Wes

You may try this old trick for positive numbers, replace + with – for negative:

i_rounded = 10 * ((i + 5) / 10);
