Elemental Intrinsic Function (Generic): Converts an integer to double-precision real type.
result = DFLOAT (a)
a |
(Input) Must be of type integer. |
The result type is double-precision real (by default, REAL(8) or REAL*8). Functions that cause conversion of one data type to another type have the same effect as the implied conversion in assignment statements.
