Because out(1,3) is only displayed to four decimal places, it is possible that it's value is actually 3.99999999999999999 or something like that. Because it's value is slightly less than 4, fix() returns 3 for that entry.

The format displays the value rounded to the nearest integer. The fix function rounds toward zero (for both positive and negative numbers).
Example
format long g
R1C2 = 3.9999999999
format short g
Q1 = R1C2
Q2 = fix(R1C2)
R1C2 =
3.9999999999
Q1 =
4
Q2 =
3
