Zoho Sheet computation bug

Zoho Sheet computation bug

This is my 1st use of this forum.  Forgive (& correct) me if I'm not on protocol or if there is an existing forum on this.

Zoho sheet had a bug years ago that I brought to the attention of Zoho at the time.  I'm super impressed with the new sheet and writer applications and am using them as default.  However the same bug still remains and that bugs me. 

As an example, put into cell A1 the number 0.05 and into A2 the formula A1*2  then drag A2 down to A31

Below is the result, with the SUM of the numbers as calculated by zoho sheet at the bottom.  But the real answer should be 107374182.35 and not 107374182.35000001
