Could you also update version information in cpp/src/arrow/vendored/fast_float/README.md?
(It's better that you update cpp/src/arrow/vendored/fast_float/update.sh to update README.md automatically.)

Could you fix build error?

If we use gsed, it works only on macOS (and *BSD).

Do you really want to use 3.10.1?
It seems that the latest version is 5.2.0: https://github.com/fastfloat/fast_float/releases

after 3.10.1 they started using c++ 20 and it cause a lot of build errors. In reality - we just need in parse_number.h

#ifdef FASTFLOAT_ALLOWS_LEADING_PLUS // disabled by default if (*first == UC('+')) { ++first; }

OK. Could you describe it in descriptions of the PR and the associated issue?

kou · 2023-07-06T02:25:20Z

It seems that we need to define FASTFLOAT_ALLOWS_LEADING_PLUS=1 explicitly to support +Infinity.
Do you want to do it in this pull request or in a follow-up pull request?

xxlaykxx · 2023-07-06T08:21:20Z

@kou i'm not sure that everyone need this - for my side, we can just build it with -DFASTFLOAT_ALLOWS_LEADING_PLUS option for enabling this functionality.

kou · 2023-07-06T21:22:40Z

I'm not familiar with +Infinity needs but it seems that +Infinity is useful for all cases. So I think that it's better that we always set FASTFLOAT_ALLOWS_LEADING_PLUS=1.

Could you share your use-case?
Could you also share downsides when we always set FASTFLOAT_ALLOWS_LEADING_PLUS=1?

xxlaykxx · 2023-07-07T10:06:26Z

not sure that downsides exist with using FASTFLOAT_ALLOWS_LEADING_PLUS 1.

My user case - in dremio some customer want to parse infinity value with + sign when they use gandiva impl of cast varchar to double/float function(same logic exist in Java implementation for cast function). So we want to add this to arrow side too

kou

OK.
Let's enable +Infinity unconditionally.

If we define this here, this change will be discarded when we update fast_float next time.
And could you also add a Gandiva test to check +Infinity is accepted or not?
