Math calculations incorrect

There seem to be some problems with using the math functions in grid and using floats:

edn , edn , ron[=c1*c2]

  • will produce -

1.5 , 12 , 12

This also seems to be the case in the example: … _math.html

I use dhtmlxgrid_math.js v.3.5 build 120822, included in a compiled file. Can I apply a path file to overrule the math functions to use floats instead of integers? How could I best override the function eXcell_math(a) ? Just redefining it does not seem to work.

Please, open ticket at so we can provide you the latest fixed dhtmlxgrid_math.js
