[1.7.1.2] Combinations rounding issue leads to incorrect prices

[pepichoc]

Hi ,

I can't put my client website in production because of a rounding issue on combinations. This is the way to reproduce the bug :

(On a combination ) 

• Set price impact HT to 216.666667 (so the TTC is 260)
• Save and go back to the catalog
• Edit the product again
• Combinations tab : Prices seem OK
• Save and go back to the catalog
• Edit the product again
• Price impact HT is now 216,000000 (so the TTC is 259.2)

 

I tried on a fresh install and the issue is still occurring.

 

I can't tell my client not to go on the product page edition... 

 

Does anyone have the same problem ?

 

Thank you
