Description:
------------
If a float value is written to a character field ('C') all decimals are
discarded, and only the integral part of the number is written. Also,
the number is right padded to the field length. This regression has been
introduced by fixing bug #39305.


Test script:
---------------
<?php

$filename = __DIR__ . DIRECTORY_SEPARATOR . 'dbase-trunc.dbf';

$db = dbase_create($filename, [['FLOAT', 'C', 15]]);

dbase_add_record($db, [123.45]);
var_dump(dbase_get_record_with_names($db, 1));


Expected result:
----------------
array(2) {
  ["FLOAT"]=>
  string(15) "123.45         "
  ["deleted"]=>
  int(0)
}


Actual result:
--------------
array(2) {
  ["FLOAT"]=>
  string(15) "            123"
  ["deleted"]=>
  int(0)
}
