Using decimal numbers
Use the function to convert ColdFusion data into BigDecimal format before you pass the value to a .NET
JavaCast
function, as in the following example:
<cfset netObj.netFunc(javacast("bigdecimal","439732984732048"))>
ColdFusion automatically converts returned decimal and System.Decimal values to ColdFusion string
representations.
Ensuring decimal and date/time conversions
ColdFusion converts .NET decimal or System.Decimal types only if the proxy for System.Decimal is a value type proxy.
Similarly, it converts .NET System.DateTime values to ColdFusion Date-time values only if the proxy for
System.DateTime is a value type proxy. The ColdFusion server always uses value proxies when it generates these
proxies. If you use the JNBProxyGUI.exe tool to generate the proxy, however, make sure to generate the proxy for
System.Decimal as value type.
Converting data to System.Object type
When a .NET method specifies
as the argument type, and you want to pass primitive values as arguments to that method, use the
to identify the data conversion. Once ColdFusion knows the data type, it automatically converts to the appropriate
.NET type. Here is the table that describes the conversion rule from ColdFusion type to .NET type.
.NET Type
bool / System.Boolean
bool[] / System.Boolean[]
char / System.Char
char[] / System.Char[]
double / System.Double
double[] / System.Double[]
float / System.Single
float[] / System.Single[]

If a .NET argument is of type System.Object, ColdFusion Strings are converted directly.

ColdFusion cannot convert System.object instances returned by .NET methods to
ColdFusion types, but you can access them using the Object methods.
