Detailed Description

Generate and return the result of comparing the values of two input containers of scalar values using the < operator.

Parameters
[in]con1: The input scalar or array of the same rank and shape as the input array-like con2 of,
  1. type css_type
  2. type csi_type
  3. type csl_type
  4. type csc_type
  5. type csr_type
  6. type css_pdt
  7. type csi_pdt
  8. type csl_pdt
  9. type csc_pdt
  10. type csr_pdt
[in]con2: The input scalar, or array of the same rank as the input array-like con1, of the same type and kind as con1.
Returns
itis : The output scalar or array of the same shape as the input array-like arguments of type logical of default kind LK containing the result of the comparison of the values of the two input containers of scalar values via the < operator.


Possible calling interfaces

use pm_container, only: operator(<)
logical(LK) :: itis
itis = con1 <= con2
This module contains the derived types for generating allocatable containers of scalar,...
Warning
The ranks and sizes of all array-like input arguments must match.
Remarks
The procedures under discussion are pure.
The procedures under discussion are elemental.

Bug:

Status: Unresolved
Source: GNU Fortran Compiler gfortran version 10.3-11
Description: The elemental implementations of the procedures under this generic interface yield incorrect results with gfortran 10.3.
Remedy (as of ParaMonte Library version 2.0.0): Currently unknown.
Todo:
Very Low Priority: The functionality of this generic interface can be extended to input arrays of higher rank.
