<function>bcpow</function> podría devolver un resultado con menos dígitos tras el punto
|

decimal que los indicados en el parámetro <parameter>scale</parameter>.

Esto sucede únicamente cuando el resultado no necesita toda la precisión
|
|
disponible por <parameter>scale</parameter>. Por ejemplo:

<title>Ejemplo de escalado de <function>bcpow</function></title>
