.SH DESCRIPCIÓN
La función \fBdrem()\fP calcula el resto de la división de \fIx\fP entre
\fIy\fP. El valor devuelto es \fIx\fP - \fIn\fP * \fIy\fP, donde \fIn\fP
es el cociente de \fIx\fP / \fIy\fP, redondeado al entero más cercano.
Si el cociente es ½, se redondea al número par.
.SH "VALOR DEVUELTO"
La función \fBdrem()\fP devuelve el resto, a menos que \fIy\fP sea cero,
fallando entonces la función y poniendo EDOM en \fIerrno\fP.
.SH "ERRORES"
.TP
.B EDOM
El denominador \fIy\fP es cero.
