Here ``digit`` is a Unicode decimal digit (character in the Unicode general Case is not significant, so, for example, "inf", "Inf", "INFINITY", and
category ``Nd``). Case is not significant, so, for example, "inf", "Inf", "iNfINity" are all acceptable spellings for positive infinity.
"INFINITY", and "iNfINity" are all acceptable spellings for positive
infinity.
