Round up function to nearest decimal

abcda — Mon, 14 Aug 2017 18:28:33 GMT

I'm trying to perform a roundup function to mimic the function in Excel where I want to round up to the nearest decimal.

For example I would like to round -0.2011 to -.202

I've tried round, ceil, and floor but I can't seem to get it to round at the decimal level, only the integer level.

Any help would be greatly appreciated.

Thanks!

newvalue=round(value+0.0005,0.001);

newvalue=ceil(1000*value)/1000;

If you are familiar with CEIL and FLOOR, you can probably do this yourself.

First, multiply by 1000. Then apply CEIL or FLOOR (might depend on whether the number is positive or negative). Then divide by 1000.

Be careful when you say rounding up or rounding down. To the mathematician, -0.2011 to -0.202 is rounding down.
