NonNegative[x] gives True if x is a non-negative number.

Evaluate different types of numbers: In[1]:=NonNegative[{1.6, 3/4, Pi, 0, -5, 1 + I, Sin[10^5]}] Out[1]={True, True, True, True, False, False, True} Quantities that are not NumericQ remain unevaluated: In[2]:=NonNegative[{x, Sin[y]}] Out[2]={NonNegative[x], NonNegative[Sin[y]]}
