User is using the IRS mileage rate of $0.545, but Core is rounding it to $0.55. How do you fix this rounding issue?
You can change the decimal settings for your company at the global level from the Global Settings > User Interface screen. The rate is set to 2 places of decimal by default; charge amount is set to 2 places of decimal, and so on. However, you can change these defaults by specifying your preferred decimal value for Rate and Units.
