UInt64 Class
A UInt64 is an intrinsic data type in REALbasic. It is an unsigned integer that uses eight bytes of storage.
It has a range of 0 to 2^64-1. The default value of an UInt64 is 0.
Notes
If either operand of an integer arithmetic expression is a 64-bit value, the result will be a 64-bit value. If both operands are 32 bits or smaller, the result will be a 32-bit value. If either operand of an arithmetic expression is signed, the result will be signed; the result will only be unsigned if both operands are unsigned.
REALbasic offers both signed and unsigned integer data types that use one, two, four, or eight bytes of memory. The following table summaries these data types.
Data Type | Number of Bytes | Range |
Int8 or Byte | 1 | -128 to 127 |
Int16 | 2 | -32,768 to 32,767 |
Int32 or Integer | √ | -2,147,483,648 to 2,147,483,647 |
Int64 | 8 | -2^63 to 2^63-1 |
UInt8 | 1 | 0 to 255 |
UInt16 | 2 | 0 to 65535 |
UInt32 | √ | 0 to 4,294,967,295 |
UInt64 | 8 | 0 to 2^64-1 |
