Detailed Description

Generate and return .true. if the input string collectively represents an integer, a real, or a complex number.

Parameters

[in]

str

: The input scalar or array of arbitrary rank of type character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU).

Returns

strIsNumber : The output scalar or array of the same shape as the input str of type logical of default kind LK whose value is .true. corresponding to each element of the input str if the element is an integer, a real, or a complex number, otherwise it is .false..

Possible calling interfaces ⛓

use pm_strASCII, only: isStrNumber
use pm_kind, only: LK
logical(LK) :: strIsNumber
 
strIsNumber = isStrNumber(str)

Remarks

The procedures under discussion are pure.

The procedures under discussion are elemental.
