// A condition is applied to check if negative or zero values are present in the dataset.
// If yes, then a near-zero value is applied to allow the computation of the logarithmic value
// If a value is zero, this simplification is acceptable
// If a value is negative, then it is not acceptable and the data of the particular column of
// logarithmic values should not be used by interpolation methods.
//
// Therefore, G4LogLogInterpolation and G4LinLogLogInterpolation should not be used if negative values are present.
// Instead, G4LinInterpolation is safe in every case
// SemiLogInterpolation is safe only if the energy columns are non-negative
// G4LinLogInterpolation is safe only if the cross section data columns are non-negative
