Description
Represents a type for numbers that can be represented with floating-point notation.
- Note: The Real48 type is only maintained for backward compatibility; using Real48 is discouraged. Use Single or Double instead.
The Real48 type is maintained for backward compatibility. The size, in bytes, of a Real48 value is 6. Real48 is equivalent to the 6-dyte Real in old Pascal versions.
Because its storage format is not native to the Intel processor architecture, it results in slower performance than other floating-point types.
The range for the Real48 type is from 2.9 x 10^-39 through 1.7 x 10^38.
