.SH DESCRIPCIN
La funcin \fBexp()\fP devuelve el valor de e (la base de los
logaritmos naturales) elevado a la potencia \fIx\fP.
.PP
La funcin \fBlog()\fP devuelve el logaritmo neperiano de \fIx\fP.
.PP
La funcin \fBlog10()\fP devuelve el logaritmo decimal de \fIx\fP.
.PP
La funcin \fBpow()\fP devuelve el valor de \fIx\fP elevado a \fIy\fP.
.SH "ERRORES"
Las funciones \fBlog()\fP y \fBlog10()\fP pueden devolver los
siguientes errores:
.TP
.B EDOM
El argumento \fIx\fP es negativo.
.TP
.B ERANGE
El argumento \fIx\fP es cero. El logaritmo de cero no est definido.
.PP
La funcin \fBpow()\fP puede devolver el siguiente error:
.TP
.B EDOM
El argumento \fIx\fP es negativo e \fIy\fP no es un valor entero.
Esto dara un nmero complejo.
