.SH DESCRIPCIÓN
.BI expm1( x )
devuelve un valor equivalente a `exp (\fIx\fP) - 1'. Se
computa de tal manera que es exacto incluso si el valor de \fIx\fP es
cercano a cero: un caso donde `exp (\fIx\fP) - 1' sería inexacto
debido a la sustracción de dos números que son casi iguales.
.PP
.BI log1p( x )
devuelve un valor equivalente a `log (1 + \fIx\fP)'. Se computa de tal
manera que es exacto incluso si el valor de \fIx\fP es casi cero.
