Rounding error in hourly paid rates

There is a rounding error when calculating hourly pay.

For example: 83.41 hours @ £12.50 per hour = £1042.625 which should be rounded UP to £1042.63 but instead is being truncated/rounded down to £1042.62

As someone who spent 20 years in software development I believe this should have found in the testing stages with rigorous enough test data. This is urgent; staff are being underpaid
