Increase the number of digits for the float type

[Matthieu]

Hi,

I need to store a float with a huge precision (8 digits after decimal).
In the documentation, I find that for a float it's 16,4.

I've found a patch that increase the number of digits to 19,4. https://support.zabbix.com/secure/at...recision.patch

But I don't well understand, how it works, somebody can help me to modify it to update the float definition to 20,8 (I think it's a good value and that can help other Zabbix user).


Thanks in advance

Update:

Now I've all my digits in DB but if I check the value displayed in "latest data", I've only 6 digits after the decimal (my DB has 8). I've try to modify defines.inc.php with these values:

define('ZBX_UNITS_ROUNDOFF_THRESHOLD', 0.00000001);
define('ZBX_UNITS_ROUNDOFF_UPPER_LIMIT', 8);
define('ZBX_UNITS_ROUNDOFF_MIDDLE_LIMIT', 8);
define('ZBX_UNITS_ROUNDOFF_LOWER_LIMIT', 8);
define('ZBX_PRECISION_10', 10);

But same issue...
