From 271ac66098e3941f137ab1f72e79bcf19fdc88f5 Mon Sep 17 00:00:00 2001

Subject: [PATCH] =?UTF-8?q?fix(forms):=20=D0=B8=D1=81=D0=BF=D0=BE=D0=BB?=
 =?UTF-8?q?=D1=8C=D0=B7=D0=BE=D0=B2=D0=B0=D1=82=D1=8C=20format=5Fdecimal?=
 =?UTF-8?q?=20=D0=B4=D0=BB=D1=8F=20input=20type=3Dnumber?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Заменён floatformat на format_decimal в полях input type="number",
чтобы числа всегда использовали точку как десятичный разделитель,
независимо от локали. Это исправляет ошибки парсинга в браузере.
