Correction to sentence

[reagan83]

Chapter 1: "A Guided Tour"

The bullet point that contains this sentence: "For example, in many languages, 1 / 3 is zero, but 1 / 3.0 is a third. OCaml requires you to be explicit about which operation you're doing."

It is syntactically incorrect.

The sentence should read (note the additional period after the 1 and the divisor):

For example, in many languages, 1 / 3 is zero, but 1. /. 3.0 is a third. OCaml requires you to be explicit about which operation you're doing.

This is intentionally not OCaml syntax. I think the idea is to show what some languages allow and that OCaml is stricter and requires you to be explicit.

Came here to report the same thing - but my comment was that it just seems wrong - replacing "For example, in many languages" with "For example, in OCaml" would correct it.

OCaml version 4.14.2
Enter #help;; for help.

# 1 / 3;;
- : int = 0
# 1.0 /. 3.0;;
- : float = 0.333333333333333315

Python 3.12.3 (main, Apr  9 2024, 08:09:14) [Clang 15.0.0 (clang-1500.3.9.4)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> 1 / 3
0.3333333333333333
>>> 1.0 / 3.0
0.3333333333333333

And if it's not OCaml syntax, what other language uses /.? Can you take another look at this?

For the record, my printed copy (2022) reads:

"For example, in many languages, 1 / 3 is zero, but 1.0 /. 3.0 is a third."

I claim it should read:

"For example, in OCaml, 1 / 3 is zero, but 1.0 /. 3.0 is a third."
