setMathRound problems

I am trying do to simple math in a column, like the example here: … math2.html

However, even when I do a mygrid.setMathRound(8), it truncates the value to a simple integer. How do I fix this to get the ron[=c4*c5] formula to deal with the decimals?

That issue was fixed in the 3.0 or 3.6 version of the grid.
Please, try to update your dhtmlxgrid. If the problem still occurs for you please, provide with a complete demo, where the problem can be reconstructed locally.
