# DNUM

Elemental Intrinsic Function (Specific): Converts a character string to a REAL(8) value. This function cannot be passed as an actual argument.

result = DNUM (i)

i | (Input) Must be of type character.

## Results

The result type is REAL(8). The result value is the double-precision real value represented by the character string i.

## Example

DNUM ("3.14159") has the value 3.14159 of type REAL(8).

The following sets x to 311.0:

      CHARACTER(3) i
      DOUBLE PRECISION x
      i = "311"
      x = DNUM(i)
