Generate and return an array of size two containing the minimum and maximum values of a sequence of values in the first and second elements, respectively.
More...
Generate and return an array of size two containing the minimum and maximum values of a sequence of values in the first and second elements, respectively.
Note that complex values are compared lexicographically.
However, when the input sequence is a scalar string, the individual characters comprise the elements/values that are compared against each other.
See pm_complexCompareLex and pm_container for more information on the relevant lexical comparison operators.
Also, note that a logical .false. is less than .true. in this module.
- Parameters
-
| [in] | array | : The input scalar sequence of,
-
type
character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) of arbitrary len type-parameter,
or an array of,
-
type
character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) of arbitrary len type-parameter,
-
type
integer of kind any supported by the processor (e.g., IK, IK8, IK16, IK32, or IK64),
-
type
logical of kind any supported by the processor (e.g., LK),
-
type
complex of kind any supported by the processor (e.g., CK, CK32, CK64, or CK128),
-
type
real of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128),
-
type css_pdt of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) or
-
type css_type of default kind SK,
containing the values whose lexicographic minimum and maximum values are to be found.
|
- Returns
minMaxVal : The output scalar of,
-
type
character of length 2 of the same kind as the input scalar array rank 0 of type character,
or otherwise, vector of shape (1:2) of the same type and kind (and length-type parameter) as the input array of rank 1, containing minval(array) in the first element and `maxval(array) in the second element.
-
If the input
array is a scalar of type character of arbitrary length-type parameter, then minMaxVal(1) will be set to the largest value for the corresponding character kind in the processor collating sequence.
-
If the input
array is a vector of size zero, then minMaxVal(1) will be set to the largest value for the kind of minMaxVal(1).
-
If the input
array is a vector of containers, then the val component of minMaxVal(1) will remain unallocated on output.
-
If the input
array is a scalar of type character of arbitrary length-type parameter, then minMaxVal(2) will be set to the smallest value for the corresponding character kind in the processor collating sequence.
-
If the input
array is a vector of size zero, then minMaxVal(2) will be set to the smallest value for the kind of minMaxVal(2).
-
If the input
array is a vector of containers, then the val component of minMaxVal(2) will remain unallocated on output.
