Description

Represents a double-precision floating-point value.

Use this floating-point format for high accuracy operations. For low accuracy operations, use single-precision floating-point values (Single). The computational time will decrease as the precision lessens. For very high accuracy operations, use Extended.

The size of Double is 8 bytes.
