15% discount all shop but need price round down (and doesn't work)

[ashtar_cl]

HI:

Platform: Prestashop 1.7.2

Price with no decimals.

 

 

I put all my shopping with 15% discount (Catalog -> Discount ->Catalog Rules) put my prices all "round up"  (ej: 34961.5 --> 34962) but I NEED "round down"

so 34961.5 must be 34961.

 

I check all option on Admin  -> General -> Round options but allways round up, not down.

 

Can anybody help?

 

Thanks.
