dmath.exp(-172) != dmath.exp(Decimal(-172)) != math.exp(-172) == exp(-172) #3
Description
What steps will reproduce the problem?
______________________________________
>>> import math,dmath,decimal
>>> math.exp(decimal.Decimal("-172"))
2.0014701280414429e-75
>>> dmath.exp(decimal.Decimal("-172"))
Decimal("-8.573821946135526241845525610E+43")
>>> dmath.exp(-172)
-218L
What is the expected output? What do you see instead?
______________________________________
maxima (a CAS) says exp(-172) == 2.0014701280414429E-75
