Assuming your formula is correct, checked longhand in Python 3.8.0 using the math library:

>>> math.exp((0.5-0.01125)*0.5)/(1.0+math.exp((0.5-0.01125)*0.5))
0.5607915159336736
>>> math.exp((0.5-0.3581)*0.5)/(1.0+math.exp((0.5-0.3581)*0.5))
0.5177300630065548
>>> math.exp((1.0-0.005268)*25)/(1.0+math.exp((1.0-0.005268)*25))
0.9999999999841571
>>> _

So your rounded values seem OK.
Again this assumes that your formula is correct.
