The following table describes the supported castings in each ABL parameter mode (INPUT and OUTPUT) between the ABL INT64 type and XML Schema.

Table 1. ABL data type cast—INT64
For this XML Schema type . . . In this ABL parameter mode . . . OpenEdge . . .
string normalizedString INPUT Serializes the ABL parameter into the XML Schema value as if the ABL STRING( ) function was called on the INT64 value.
OUTPUT De-serializes the XML Schema value as if the INT64( ) function was called on string value.
boolean INPUT Serializes an INT64 value of 0 to false and all other values to true.
OUTPUT De-serializes a value of false to an ABL INT64 value of 0, and de-serializes a value of true to an INT64 value of 1.
decimal INPUT Serializes the ABL parameter into the SOAP request message according to the XML Schema serialization rules.
OUTPUT De-serializes the XML Schema value as if the INT64( ) function was called on the serialized ABL DECIMAL value. This rounds any positions after the decimal point. If the XML Schema decimal value is outside the range of an ABL INT64, the AVM raises a run-time error.
float INPUT Translate the INT64 to a C value, cast to a C float value, and then serialize the ABL INT64 value to a float according to the XML Schema rules. Some of the least significant digits of the INT64 value are lost if the number of digits in the value is large.
OUTPUT De-serializes the XML Schema value into a C float value and then cast the C value to ABL INT64. If the XML Schema value overflows or underflows an ABL INT64, the AVM raises a run-time error.
double INPUT Translate the INT64 to a C value, cast to a C double value, and then serialize the value to a double according to the XML Schema rules.
OUTPUT De-serializes the XML Schema value into a C double value and cast it to an ABL INT64. If the XML Schema value overflows or underflows an ABL INT64, the AVM raises a run-time error.

 INPUT Serializes the ABL parameter into the SOAP request message according to the serialization rules for the XML Schema data type.
OUTPUT De-serializes the XML Schema value as if the ABL INT64( ) function was called on the value. If the XML Schema value is outside the valid range of an ABL INT64, the AVM raises a run-time error.
long INPUT Serializes the ABL parameter into the SOAP request message according to the XML Schema serialization rules.
OUTPUT De-serializes the XML Schema value as if the ABL INT64( ) function was called on the value.

 INPUT Serializes the ABL parameter into the SOAP request message according to the serialization rules for the XML Schema data type. If the ABL INT64 value is outside the valid range of the XML Schema type, the AVM raises a run-time error.
OUTPUT De-serializes the XML Schema value as if the ABL INT64( ) function was called on the value.
