Description:
Zero on y axis of a graph in Libreoffice Calc is not shown as zero but as a
very small number that contains many digits such as 2.7755576156289E-17. 

Steps to Reproduce:
1. Input the following values in the range A1:B3 of a sheet in Calc: 
   X    Y
   A  -0.1
   B  0.09
2. Select the range A1:B3 and click the icon of "insert chart" on the toolbar,
and click the finish button.
3. Double click the y axis to open a window to modify the scale. Click the
checkbox "Automatic" on the right side of Maximum on the scale tab.
4. Change the maximum value from 0.15 to 0.1. Click OK. 

Actual Results:
Zero value on the y axis is shown as 2.7755576156289E-17.


Expected Results:
Zero value on the y axis should be shown as zero exactly.


Reproducible: Always


User Profile Reset: Yes



Additional Info:
Sometimes, it is necessary to adjust scales of multiple graphs to match their
scales into one for easy comparisons. When this bug occurs, it becomes very
difficult and cumbersome to detour this problem by trying many different scales
to avoid this problem.
