HP Prime complex division problem in CAS

[lyuka]

In CAS, instead of complex division z1 / z2, both z1 * inv(z2) and z1 * z2^-1 were OK.

(1.e154+2.e154*i)*(2.e154+1.e154*i)^-1 → 0.8+0.6*i
(1.e154+2.e154*i)*inv(2.e154+1.e154*i) → 0.8+0.6*i

But the history display when using inv() was converted to fractional notation.
Therefore, it is not possible to distinguish from the history whether division or reciprocal multiplication was used even though the calculation results are different.
