Float filed approximation

[buothz]

General question about processwire, when I create a float field and insert data system truncates the decimal point, and this is not obvious if I type the numbers 2.090000 ...

But if I want to:

- 2 exact decimal (eg 2.40 / 69.70 -> now instead of 2.4 / 69.7)

- And always keep at least 2 decimal places (eg 2,00 / 69,00 -> instead I out 2/69)

where can I do? I can choose how many decimal places to round off the menu (in fact, I put 2), but I would like to, just for the field, keep the zeros and rounding to 2 decimal places ...

Thanks in advance.

The default precision value is 0. I can update this to assume no precision value until it is specifically set ... I think this makes sense--thanks.

The precision field is for rounding, not formatting. I think what you want is number_format(). You could do this in your output:

$value = number_format($page->float_value, 2); 

I could add this formatting in as a configuration option with FieldtypeFloat too, but once formatted, the value is a string, not a float. And I'm not sure it's wise for us to have this Fieldtype returning strings rather than floats.

There are also localization considerations with number formatting (decimal type and thousands separator), which are also the job of number_format.

perfect, resolved with

$value = number_format($page->float_value, 2); 

u're a genius!
