To be honest, you have been slandering a lot, also in previous discussions, to get what you wanted. This is not a healthy way of discussion, nor does it help in any way. There have been many people willing to listen and agree with you on points; and this is exactly what discussion is all about, bu

[Numpy-discussion] Large numbers into float128

Hi, Can anyone think of a good way to set a float128 value to an arbitrarily large number? As in v = int_to_float128(some_value) ? I'm trying things like v = np.float128(2**64+2) but, because (in other threads) the float128 seems to be going through float64 on assignment, this loses precisio
