Hello and welcome to the forum,
While binary mibht be "better", please re-read closely what Robert has posted. . .
Unless the field is being references tens (or hundreds) of millions of times in your code, no you will not see any significant improvement by converting to BINARY.
With the newer, extremely more powerful processors, this is rarely a ocncern.
when a programmer develops produces inefficient code when it would take no more time to code efficiently, they are doing a disservice to their employer.
