Petascope_Fix the problem with comparison of coefficients from WCST_Import

[Bang Pham Huu]

There is a problem with the comparison of coefficients from WCST_Import when importing a grib file of ECMF.

The result is double, e.g:

irregular datetime (arrow library).
0.04166666666666666666666666667

However, in Petascope, the coefficient is in BigDecimal and value is different, e.g:

0.04166666666666666666666666666666666666666666666667

So a fix needed to add a small epsilon number to consider both numbers are the same.

[Dimitar Misev]

add a small epsilon to what number?

[Bang Pham Huu]

Replying to dmisev:

add a small epsilon to what number?

it will be fixed in Petascope add epsilon to BigDecimal to compare.
