Bug: extrafields type double wrong length

[fbosman]

Bug

Extrafields with type float need specific number of decimals. The system always imposes 24,8 as length and always shows 2 decimals.

Environment

• Version: 9.04
• OS: ubuntu
• Web server: apache
• PHP: 7.x
• Database: mariadb
• URL(s): [Affected URL(s)]

Expected and actual behavior

Extrafields with type float need specific number of decimals. The system always imposes 24,8 as length and always shows 2 decimals.

Suggested implementation

I did get it to work somehow:

In module core/actions_extrafields_inc.php

alter line 30: $extrasize=GETPOST('size','int');
to
$extrasize=GETPOST('size','intcomma');
otherwise a float will always have length 24,8

in module core/class/extrafields.class.php:
alter line 1543:
if (!empty($value)) {
$value=price($value);

to
if (!empty($value)) {
// $value=price($value);
$sizeparts = explode(",",$size);
$number_decimals = $sizeparts[1];
$value=price($value, 0, $langs, 0, 0, $number_decimals, '');

Suggested steps

I'm not very good in php, hope this is right and can be merged into the core.
