Description

Represents a type for numbers that can be represented with floating-point notation.

The Comp (computational) type is native to the Intel processor architecture and represents a 64-bit integer. It is classified as real, however, because it does not behave like an ordinal type (for example, you cannot increment or decrement a Comp value.) Comp is maintained for backward compatibility only. Use the Int64 type for better performance.

The range for the Comp type is from -2^63+1 through 2^63-1. The size in bytes of a Comp value is 8.
