On payment screen, take currency input in cents e.g 259 should be $2.59

Hello,
   In my existing legacy cash register, employees are used to entering 259 for $2.59 cents.  In SambaPOS,  we have to enter 2,59 which they make mistake and it shows up as customer gave $259 rather than $2.59.

How should I modify the code to support this?
