The scalb() family of functions shall compute x*r^n, where r is the radix of the machine's
floating-point arithmetic.
According to LSB, the functions shall set EDOM error code when x is zero and n is +Inf, or x is Inf and n
is -Inf and ERANGE when overflow occurs.
But the functions sets error code EOK in these cases.
