FieldtypeFloat

float — returns 0.0 when blank (not ''). Zero and blank are equivalent due to zeroNotEmpty behavior (see Notes).

// Get
$page->float_field         // float 0.0 when blank)
(float) $page->float_field // same as above; explicit cast for clarity

// Set
$page->float_field = 3.14;
$page->float_field = '';   // clear the value
$page->save('float_field');

$pages->find('float_field=3.14');
$pages->find('float_field>1.0');
$pages->find('float_field=""');  // no value
$pages->find('float_field>=1.5, float_field<=9.5'); // range

zeroNotEmpty: by default 0.0 and blank are equivalent — there is no way to distinguish "no value" from "zero" unless zeroNotEmpty is disabled in the field settings.

• Default precision is 2 decimal places. Set precision to a different integer, or -1 to disable rounding.
• Column type is float (single-precision) by default. Switch to double for higher precision when needed.
• Compatible fieldtypes: FieldtypeFloat, FieldtypeInteger, FieldtypeDecimal, FieldtypeText.
• Database column: float NOT NULL or double NOT NULL.
