The two solutions may differ when [[comparison tolerance]] is not zero, because Index Of uses tolerant comparison but Grade does not. The first solution will return a smaller index if an element that is tolerantly but not exactly equal to the minimum is found at that index. | The two solutions may differ when [[comparison tolerance]] is not zero, because Index Of uses tolerant comparison but Grade does not.

Reducing over an empty axis yields the largest representable number, as that is the identity element for Minimum. This value is usually <source lang=apl inline>∞</source> (for dialects that support [[infinity|infinities]]) or <source lang=apl inline>1.797693135E308</source> (with 64-bit [[float]]s) or <source lang=apl inline>1E6145</source> (with 128-bit [[decimal float]]s). | |||
