decimal form ICD-9 codes are not ambiguous if the leading zeroes are dropped. Some short-form ICD-9 codes would not be ambiguous, e.g. "1" but many would be problematic, so no function is provided to do this for short-form codes. This is the inverse of icd9AddLeadingZeroesDecimal
icd9DropLeadingZeroes(icd9, isShort)icd9DropLeadingZeroesDecimal(icd9Decimal)
icd9DropLeadingZeroesShort(icd9Short)
icd9DropLeadingZeroesMajor(major)
is a character vector of ICD-9 codes. If fewer than five characters is given in a code, then the digits are greedily assigned to hundreds, then tens, then units, before the decimal parts. E.g. "10" becomes "010", not "0010"
