Requirent qty calculation

Hello Experts,

For an item in the BOM, the required quantity is maintained as 0.036 M.

but when it is copied for an prd order (eg., 54 quantities) , the item required qty should be 54* 0.036 =1.944 M.

but is is showing 1.94 M only,

Where is the setting for the no of digits after decimal points done?

thanks...

regards,
