[glorieux-f]

Please follow the general troubleshooting steps first:

• I read the README and followed the instructions.
• I am sure that the used CSL metadata follows the CSL schema.
• I use a valid CSL stylesheet

Bug reports:

PHP Notice: A non well formed numeric value encountered in Rendering\Number.php on line 155

citeproc-php

• Doe, J. (n.d.). Edition not ordinal (2ndnd ed.).

Zotero dsektop

• Doe, J. (n.d.). Edition not a simple number (2nd ed.).

«“2nd” tests “true”» Constraint/IsNumeric.php#L45

quick fix Rendering\Number.php#L152

public static function ordinal($num): string
{
    if (!is_numeric($num)) {
        return $num;
    }

Used CSL stylesheet:

apa.csl#L1040

  <if is-numeric="edition">
    <group delimiter=" ">
      <number variable="edition" form="ordinal"/>
      <label variable="edition" form="short"/>
    </group>
  </if>

Used CSL metadata
