Parsing numbers starting with 0 is not supported about atoi_simd HOT 9 CLOSED

I see, thanks for clarification.

Parsing numbers with leading zeroes is something people also need to do, and I think this library could do it faster than str::strip_leading_maches('0'). There are ways to quickly count leading decimal zeroes with SIMD: KholdStare/qnd-integer-parsing-experiments#2

from atoi_simd.

Actually, it fails with SIMD enabled as well. So turning SIMD on/off doesn't make any difference.

I am also getting a similar error when trying to parse 0000000000000000000000000000000000000001

The standard library implementation also handles this one correctly.

from atoi_simd.

Zeroes at the beginning of the input are not supported by the design, and I am not sure if it's needed, because it will work slower.

from atoi_simd.

Hm, it might be not that slow as I thought. Will think about it, thanks

from atoi_simd.

It works, but with length not more then type's numbers max length 2288368 (starting with 16)

from atoi_simd.

FWIW the standard library parser supports even longer sequences of leading zeroes, so that 000000000000000001 does parse correctly into a u16.

It's up to you whether you choose to support this use case.

from atoi_simd.

I just don't see any use cases. If anybody needs it, write it here, with an explanation of the use case, would be interesting to know.

Done in a separate function atoi_simd::parse_skipped
