Look at this link it gives u a different defn of frac(x)
1look ,things get simplified if u write {x}=x-[x]
as y=x(x-[x])
=x2-x[x]
which if taken in intervals (for example 0<x<1 and so on)....reduces to a quadratic equation....which can be drawn easily[1][1]

for (-1,0) it will be y=x(x+1) and y cannot be positive and hence give the result as shown
