pm_logicalCompare::operator(<=) Interface Reference

Generate and return .true. if the input logical argument lhs is less than or equal to the input logical argument rhs. More...

Detailed Description

Generate and return .true. if the input logical argument lhs is less than or equal to the input logical argument rhs.

Parameters

[in]	lhs	: The input scalar or array of the same rank and shape as rhs of type logical of default kind LK.
[in]	rhs	: The input scalar or array of the same rank and shape as lhs of type logical of default kind LK.

Returns

compares : The output object of the same type and kind as, and the higher rank of, the two input arguments lhs and rhs.

Possible calling interfaces ⛓

use pm_logicalCompare, only: operator(<=)
use pm_kind, only: LK
logical(LK) :: compares
 
compares = lhs <= rhs

Remarks

The procedures under discussion are pure.

The procedures under discussion are elemental.
