BigInteger Data Type
Stores very large whole numbers that range from -9,223,372,036,854,775,807 to 9,223,372,036,854,775,807.
This data type is a 64-bit integer.
You must add an L to the constant definition to inform AL that the integer must be interpreted and treated as a BigInteger.
If you assign -9,223,372,036,854,775,808 directly to a BigInteger variable, then you get an error when you try to compile the code. However, you can indirectly assign -9,223,372,036,854,775,808 to a BigInteger variable by using the following code.
BigIntegerVar := -9223372036854775807L; BigIntegerVar := BigIntegerVar - 1;
If you try to indirectly assign a value that is smaller than -9,223,372,036,854,775,808, or larger than 9,223,372,036,854,775,807, then you get a run-time error.
The methods supported for the BigInteger data type are:
BI := 1L; BI := 455500000000L;
