We have the questions asking about farmer land use in the order
How many hectare of cultivated land you have ? answer in decimal
1.1 How many hectare of CROP 1 cultivated land you have? answer in decimal
1.2 How many hectare of CROP 2 cultivated land you have? answer in decimal
To validate the land - 1.1 +1.2 = 1 if not it showed the message that they need to redo it
We started having problem when data collector answer as :
How many hectare of cultivated land you have ? 2.64
1.1 How many hectare of CROP 1 cultivated land you have? 2.32
1.2 How many hectare of CROP 2 cultivated land you have? 0.32
But the validating message showed the sum of 1.1. and 1.2 as: 2.6399999999999997
which has 13th decimal- and this is not match with the total number which inputted in 1 which is 2.64
