ABS Function
Returns the absolute value of x.
enabled.Usage
result = ABS(x)
Input Parameters
x—The value that is evaluated. May be of any dimension.
Returned Value
result—The absolute value of x.
Keywords
None.
Discussion
ABS is defined by:
f(x) = |x|
If x is an array, the result has the same dimension. Each element of the returned array contains the absolute value of the corresponding element in the input array.
When x is complex, the result is the magnitude of the complex number:
When x has a data type of complex, the result is double-precision floating-point. All other data types produce a result with the same data type as x.
Example
x = [-1, 2, 3, -4, 5]
PRINT, ABS(x)
; PV-WAVE prints: 1 2 3 4 5
x = COMPLEX(4, 3)
PRINT, ABS(x)
; PV-WAVE prints: 5.0000000
