Problem with the power symbol

[Sayan Kr. Das]

When you set the incoming momenta in the batch file to be p = 10**(-2) it gives cross-sections different from p = 1e-2 or p = 1E-2. When examined carefully, it is seen that the parser reads 10**(-2) as 10. So the exponent part is ignored and the cross-section returned is for p = 10.

Curiously, the program returns compatible results if you set a run parameter r such that,
p = 10**(-2 + r) and run r from 0 in one step. It gives the same result as that by setting p = 1e-2.
