Can I use logarithm in AMPL

[wanjun]

Dear all,

I want to formulate some equations like ln(z(k)) <= D,
z(k) is a variable. Is there some function or keyword used as logarithm?
Or is there some method to calculate logarithm? Thanks

Wanjun

log(x) is the natural logarithm (ln), and
log10(x) is the base-10 logarithm.
