Subject: [Caml-list] floating point input/conversion
Date: Fri, 22 Oct 2004 11:25:40 +0200	[thread overview]
Message-ID: <1098437140.3079.21.camel@localhost> (raw)

For the functions float_of_string and read_float the OCaml manual is
very vague: "Convert the given string to a float".

In fact, this sentence is wrong. For example, the number 0.1 does not
have a floating point representation, only approximations to it.

So what is the exact specification of these functions? Which number is
taken if the given string does not have a floating point representation?
The nearest one? The nearest one up to 2ulps? Is the current rounding
mode taken into account?
