Detailed Description

Return the conversion of the input value to a real value of arbitrary kind.

Parameters
[out]conversion: The output scalar or array of the same shape as other array-like arguments, of type real of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128), containing the conversion of the input value val.
  1. If the input val is a logical that evaluates to .true., then conversion = 1., otherwise conversion = 0..
  2. If the input val is a character, then conversion is the result of the List-directed I/O action read(val,*) conversion.
[in]val: The input scalar or array of the same shape as other array-like arguments, of either
  1. type character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU), or
  2. type logical of kind any supported by the processor (e.g., LK), or
whose value will be converted to an output of type real.
[out]iostat: The output integer of default kind IK, of the same rank as the input val containing the Fortran IO status error code returned by the read() statement of the Fortran standard.
On return, it is zero if and only if no error occurs during the execution of the Fortran read() statement.
Refer to the Fortran standard read/write statements for the meaning of different non-zero output values for iostat.
(optional, it can be present only if val is of type character. if missing, the program will halt upon an IO error.)


Possible calling interfaces

use pm_val2real, only: setReal
call setReal(conversion, val)
call setReal(conversion, val, iostat)
Return the conversion of the input value to a real value of arbitrary kind.
This module contains procedures and types for facilitating the conversion of values of different type...
Definition: pm_val2real.F90:43
Warning
When the input val is an array, the output iostat, if present, must also be a vector of the same shape and size as val.
Remarks
The procedures under discussion are pure.
The purity of the procedures under this generic interface break when the output argument iostat is present.
The procedures under discussion are elemental.
