Description: |
Converts a number to quad precision (REAL(16)) type. | ||

Class: |
Elemental function; Generic | ||

Arguments: |
A 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. |

**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).
