Subject: Re: [Caml-list] Create Array of floats from string
Date: Wed, 26 Apr 2017 13:02:27 +0200	[thread overview]
Message-ID: <20170426110226.GJ32215@ccellier.booking.pcln.com> (raw)

If speed is more important than readability I would avoid creating the
intermediary list of strings and go with Str.search_forward, then extract that
string and convert it to float.

If the separator is as simple as a space I'd expect String.index_from to be
slightly faster. Also consider BatString.find_all that returns an enum (of
starting positions - unfortunately we do not have BatString.split variant
returning an enum of substrings directly).

If that's not enough you'd have to use another library to parse the string, one
that would implement something like `float_of_string_from` so that you do not
have to build all those useless substrings.
