Story:
On Mars there exists a company, lets name this company Martion.
This company has an issue with some of their data, you are hired to solve the following issue.
The issue is comming from a larger input than the output, it is more work to change the output field (this impacts thousands of programs), this is why a new function must be build to get the correct data into the output field without changing the output field size.
Scenario:
Input =
EX-RATE-I
Output =
EX-RATE-O
AMT-DECIMALS
ERR-FIELD
Assignment:
Move input EX-RATE to Output EX-RATE and determine how many DECIMALS are moved to Output and note them in AMT-DECIMALS. (Pre decimal numbers are leading)
If Input EX-RATE does not fit into Output EX-RATE, move "Error" to ERR-FIELD - NOTE: it is allowed to round the decimals if possible ( You are expected to do this ).
