greatest integer is the just the nearest integral value to which a number  approaches in left hand side.
an odd function is the function which is symettrical with respect to origin,in other words if we replace x by -x then f(x) also get replaced by -f(x).
for example f(x)= sinx an odd function
because sin(-x)=-sin x
