Re: [SPAM] Re: [Quickfix-developers] price as double

[Oren M. <or...@qu...>]

The C++ fields have a setString and getString method.  You can use=20

doesn't have access to these, so it would need to be added to the API. =20=

We can also replace the DoubleField with a BigDecimal field, or add=20
BigDecimal support to the existing field type.
