void fexpr_set_arf(fexpr_t res, const arf_t x)source

void fexpr_set_d(fexpr_t res, double x)source

Sets res to an expression for the exact value of the floating-point number $x = m \cdot 2^e$ ( $m$ odd): an integer if $0 \le e \le 20$ , a fraction Div(m, 2^-e) if $-8 \le e < 0$ , and otherwise Pow(2, e), Neg(Pow(2, e)) or Mul(m, Pow(2, e)). Infinities are written as Infinity and Neg(Infinity), NaN as Undefined.
