Hello guys i'm using odoo 10..
​

i have condition 5 field type float  8 digit A,B,C,D,E

A = 1000

B = 130

C = A / B

D = 8

E = C * D

i want multiply my field like this in 8 digits 

1000 / 130 = 7.69230769

7.69230769 * 8 = 61.53846152‬

I want my field C =  7.69230769 and E = 61.53846152 show only 2 digits in view but still 8 digit in multiply..

because if i cut my field C in 2 digits only, my E will be different 0.01 from 61.53 become 61.52

7.69 * 8 = 61.52

can anyone know how to solved this?
