In constructor,
for string, we assign value to variable this way ' '
for decimal/double, how to assign value to variable in constructor?
I tried 0, but, in database, 0 is stored rather than user input in VF page. If I dont declare price/quantity, the child record is not created. wrapper class is used to create child record & price/quantity are the fields of child record.
Say, user enter 2 as price, 4 as quantity, then 2,4 should be stored in database,, but 0,0 (constructor value is stored in the database.)

Best Answer
Apex handles the type conversion of numeric constants well for Decimals so you can initialize like this if you don't care about the number of decimal places (the scale):
or like this if you want a specific number of decimal places (2 in this case):
As Rahul suggests, your problem most likely lies in other code.
