Detailed Description

Generate and return .true. if all characters of the input string collectively represent a real number.

The characters used in the representation of a real number are given by REAL_VEC_SK).
The real string must contain only these characters and must collectively represent a meaningful real 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: strIsReal : 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 a real number, otherwise it is .false..

Possible calling interfaces ⛓

: use pm_strASCII, only: isStrReal

use pm_kind, only: LK

logical(LK) :: strIsReal

strIsReal = isStrReal(str)

Warning: This procedure is sensitive to the presence of white-space characters in the string, in which case the output is .false..
The must not exist any white-space within the real number or at the beginning or the end of the string.
If there is the possibility for any trailing or preceding white-space characters in the string, pass trim(adjustl(str)) as the input argument instead.

Remarks: The procedures under discussion are pure.; The procedures under discussion are elemental.
