Purpose
Absolute value.
Class
Elemental function
Argument type and attributes
- A
- must be of type integer, real, or complex.
Result type and attributes
The same as A, except that if A is complex, the result is real.
Result value
- If A is of type integer or real, the result is |A|
- If A is of type complex with value (x,y), the result approximates
Examples
ABS ((3.0, 4.0)) has the value 5.0.
| Specific Name | Argument Type | Result Type | Pass As Arg? |
|---|---|---|---|
| IABS | any integer 1 2 | same as argument | yes |
| ABS | default real | default real | yes |
| DABS | double precision real | double precision real | yes |
| QABS 1 | REAL(16) | REAL(16) | yes |
| CABS | default complex | default real | yes |
| CDABS 1 | double complex | double precision real | yes |
| ZABS 1 | double complex | double precision real | yes |
| CQABS 1 | COMPLEX(16) | REAL(16) | yes |

Given that X is a complex number in
the form a + bi, where i = (-1)½:
- abs(b) must be less than or equal to 88.7228; a is any real value.
- abs(b) must be less than or equal to 709.7827; a is any real value.
