HumidAir wrong calculations

[JB-AM]

It seems HumidAir return grossly wrong calculations at temperatures under around 295K, 1atm.
Please try:

import iapws.humidAir as ha
a = ha.HumidAir(T=295, P=0.101325, W=0.00858)
print(a.RH)

It should return around 50%, or 0.5, but prints -0.9678.
It seems calculations at higher temperatures are right:

a = ha.HumidAir(T=323, P=0.101325, W=0.0388)
print(a.RH)

shows 0.5009.

Hi, i can't reproduce that

import iapws.humidAir as ha
a = ha.HumidAir(T=295, P=0.101325, W=0.00858)
print(a.RH)
0.597440017070571

and

a = ha.HumidAir(T=323, P=0.101325, W=0.0388)
print(a.RH)
0.5009937761563956

Maybe you're not using the last version, I'm fairly sure that error was fixed in this commit, 0a687f6

You’re right. I simply installed iapws from pip (pip install iapws), it seems the version there is not up to date. After installing from git, the value given seems reasonnable.
But why I get :

>>> import iapws.humidAir as ha
>>> a = ha.HumidAir(T=295, P=0.101325, W=0.00858)
>>> print(a.RH)
0.5282298396607987

While you get : 0.597440017070571 which seems rather high,
I do not know…
