If the number to be dropped is less than 5, the number before it remains unchanged. Round the following number, so that the 4 is to be dropped. 2.6354 rounds to 2.635.

If the number to be dropped is greater than 5, the number before it is rounded up. Round the following number, so that the 6 is to be dropped. 9.4046 rounds to 9.405.

If the number to be dropped is 5, the number before it remains the same if it is an even number and is rounded up if it is an odd number. 2.685 rounds to 2.68 because 8 is an even number. 7.3075 rounds to 7.308 because 7 is an odd number.
