For `brob`

s: apart from `abs()`

, `log()`

, `exp()`

,
`sinh()`

and `cosh()`

, these functions return
`f(as.numeric(x))`

so are numeric; the exceptional functions
return `brob`

s.

For `glub`

s: mostly direct transliteration of the appropriate
formula; one might note that `log(z)`

is defined as
`glub(log(Mod(x)),Arg(x))`

.
