Hi. In the OEIS I run into the following line of pari code:

intnum(x=3D0, [[1], 1], 1/gamma(1+x))

Apparently, this is equivalent to

intnum(x=3D0, [+oo, 1], 1/gamma(1+x))

but the documentation doesn't mention anything like that.

I'm wondering if they are actually equivalent and why apparently [1] is
replaced by +oo in this context.

  Best regards,
