# QEXT

Elemental Intrinsic Function (Generic): Converts a number to quad precision (REAL(16)) type.

result = QEXT (a)

a | (Input) Must be of type integer, real, or complex.

## Results

The result type is 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.

Specific Name 1 | Argument Type | Result Type
--- | --- | ---
| INTEGER(1) | REAL(16)
| INTEGER(2) | REAL(16)
| INTEGER(4) | REAL(16)
| INTEGER(8) | REAL(16)
QEXT | REAL(4) | REAL(16)
QEXTD | REAL(8) | REAL(16)
| REAL(16) | REAL(16)
| COMPLEX(4) | REAL(16)
| COMPLEX(8) | REAL(16)
| COMPLEX(16) | REAL(16)
1These specific functions cannot be passed as actual arguments.

## Example

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).
