I've just downloaded 4.22 to check, and the remarks for CInt() read as follows:
Quote:

Remarks
CInt differs from the Fix and Int functions, which truncate, rather than round, the fractional part of a number. When the fractional part is exactly 0.5, the CInt function always rounds it to the nearest even number. For example, 0.5 rounds to 0, and 1.5 rounds to 2.



I use an older printed version (4.20) and the remarks are the same.
