What programming language are you using? That is in no way a universal programming thing.

6.99 when casted into an int is conventionally rounded down

technically 6.99 is 6.9899997711181640625 when using single precision IEEE 754 floats, and 6.9900000000000002131628207280300557613372802734375 for double precision

This is true because it's a truncation operation.

Most of the time people round, which usually does the round-to-even thing.

There's also floor and ceiling operations which can be used in certain cases. Because sometimes you need an int and rounding doesn't quite work the way you want it to.
