Zoho Quote / Product - Price rounding & tax issue

Hello,

I have the following challenge:

Unit price of a product is 325,2 EUR per piece net. I must apply 23% tax on it. 
325,2 EUR * 1,23% = 399,996 EUR (gross)

In Zoho Quotes - the Products Details section, when there is a 1 unit, the system is rounding up correctly the amount to 400 EUR.

However when there are 5 units...this is what the system does:

325,2 * 1,23% = 399,996 * 5 = 1.999,98 EUR (gross)

This is incorrect. It should be 2.000 EUR. 

Is there any way to correct it?

Thank you in advance for your help!
Regards,
PJ
