Double precision floating-point data type.
Dim name As Double
Dim name#
Type declaration character is #.
Double is the most efficient of the fractional data types, because the processors on current platforms perform floating-point operations in double precision. However, operations with Double are not as fast as with the integral types such as Integer.
A Double occupies 64 bit = 8 bytes with at least 15 digits of precision.
Minimum: _minDbl (-1.79769313486232e+308)
