Roundup

Great plug-in ??
Just one issue with roundup. When I use ROUNDUP(x,-5) it works great until the input is above 1,000,000 and a multiple of 100,000.
For example jazzy rounds-up 1,100,000 to 1,200,000 (I get the same result in your test page https://mundoacustico.com/sandbox/wp1/?p=89)
However, Excel leaves it at 1,100,000 with the same formula.

Is there any workaround?
