As with the previous formula, the calculated air mass reaches a maximum, and then approaches negative infinity at the horizon.

Likewise, if a is negative, it decreases to negative infinity and has a global maximum.

One can similarly replace m with negative infinity, and define:

This essentially relies on the fact that tends to negative infinity as tends to 0.

Greater than 1, there will be exponential growth towards positive or negative infinity (depending on the sign of the initial term).

If elected president, I will reduce taxes to negative infinity.

Indeed, it has extremely simple behaviour: all points except 0 will tend to positive or negative infinity.

Antinumbers are envisioned to be numbers beyond positive and negative infinity.

Division of any non-zero finite number by zero results in either positive or negative infinity.

Upon a divide by zero exception, a positive or negative infinity is returned as an exact result.
