arb_get_interval_fmpz_2exp

Synopsis#include <flint/arb.h>
void arb_get_interval_fmpz_2exp(fmpz_t a, fmpz_t b, fmpz_t exp, const arb_t x)source

Writes the exact interval of x as [a, b] \cdot 2^{\mathit{exp}} with integers a, b without common trailing zero bits.

Raises an exception if x is infinite or NaN. The integers can have as many bits as the difference of the exponents of the midpoint and the radius, so this can exhaust memory for unusual balls.
