You posted the same question about "3" and I will give the same answer here: it depends upon specifically which definition of "decimal fraction" you are using. The Wikipedia definition I posted before would say "no, -0,5 is not a decimal fraction" but not because it is negative. That definition would say that "-0,5" is not a fraction because it is not a fraction but that -5/10, which is just a different way of writing -0,5, is a decimal fraction.

It's hard to say since -0.5 = -1/2 = 1/-2 = -(1/2). However -1 < 2 while 1 > -2.
