y = inf
The returned type is a 64-bit float, but demotion to 64 bits preserves the infinity.
Note that infinities are not preserved under type conversion to integer types (see the examples below).
--> inf*0
ans =
nan
--> inf*2
ans =
inf
--> inf*-2
ans =
-inf
--> inf/inf
ans =
nan
--> inf/0
ans =

--> inf/nan
ans =

Note that infinities are preserved under type conversion to floating point types (i.e., float, double, complex and dcomplex types), but not integer types.

ans =

--> complex(inf)
