const LINT&
LINT::mexp (USHORT e, const LINT& m);
Syntax:
a.mexp (e, m);
Example:
const LINT& LINT::mexp (USHORT e, const LINT& m)
{
int err;
if (status == E_LINT_INV) panic (E_LINT_VAL, "mexp", 0, __LINE__);
if (status == E_LINT_INV) panic (E_LINT_VAL, "mexp", 1, __LINE__);
err = umexp_l (n_l, e, n_l, m.n_l);
switch (err)
{
// Code as above with mexp (const LINT& e, const LINT& m)
}
return *this;
}
