I dont know if there's a function specified for this, but you could turn this into a function:
[php]
$_float = 1.9020441;
$_float = explode(".", $_float);
echo strlen($_float[1]);
[/php]

Regards :)

This variant is also possible:
[PHP]$_float = 1.9020441123;
print strcspn(strrev( $_float), '.');[/PHP]

Regards.
