Elemental Intrinsic Function (Generic): Converts a number to quad precision (REAL(16)) type.
Syntax
Results:
The result is of type REAL(16) (REAL*16). Functions that cause conversion of one data type to another type have the same effect as the implied conversion in assignment statements.
If a is of type REAL(16), the result is the value of the a with no conversion (QEXT(a) = a).
If a is of type integer or real, the result has as much precision of the significant part of a as a REAL(16) value can contain.
If a is of type complex, the result has as much precision of the significant part of the real part of a as a REAL(16) value can contain.

Examples
QEXT (4) has the value 4.0 (rounded; there are 32 places to the right of the decimal point).
QEXT ((3.4, 2.0)) has the value 3.4 (rounded; there are 32 places to the right of the decimal point).
