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`. If the input `val` is a `logical` that evaluates to `.true.`, then `conversion = 1.`, otherwise `conversion = 0.`. 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 type `character` of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU), or 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 ⛓

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.
