High Precision Number
Quite often we process very large numbers in our mapping, like Credit Card Numbers, Bank Account Number or even some scientific numbers which needs high precision. Informatica PowerCenter can process numbers up to 15 digit precision without having high precision configuration. We can't treat bigger numbers more than 15 digits as normal numbers, treating so will lead to truncation or rounding of the numbers. In this tutorial we will see how we can process high precision numbers in Informatica PowerCenter and general guidelines for using high precision configuration.
