// "PolicyFee": 0.00,
// "PolicyFeeSecondary": 0,
// "PolicyFeeHidden": 50.00,
// "PolicyFeeHiddenSecondary": 0

// We can get the floating point numbers as strings. Then convert to double
// using the appropriate string-to-double conversion for your programming language.
// For example, in C++ use atof. In C# use Convert.ToDouble.
