    en.wikipedia.org/wiki/Round_(cryptography)

    Since a single round is usually cryptographically weak, many attacks that fail to work against the full version of ciphers will work on such reduced-round variants. The result of such attack provides valuable information about the strength of the algorithm, [ 9 ] a typical break of the full cipher starts out as a success against a reduced-round ...

In both technical and informal language, a round number is often interpreted to stand for a value or values near to the nominal value expressed.

    If you want to round to whole values, you have 0 and 1 available. 0 covers -0.5 to 0.5, and 1 covers 0.5 to 1.5. 0.0 through 0.4 thus clearly convert to 0, and 0.6 through 1.0 clearly convert to 1. 0.5's range is perfectly divided in two by the ranges that 0 and 1 cover.
