IEEE_SELECTED_REAL_KIND

Module

USE, INTRINSIC :: IEEE_ARITHMETIC

result = IEEE_SELECTED_REAL_KIND ([p][,r])

At least one argument must be specified.

Results

The result is a scalar of type default integer. The result has a value equal to a value of the kind parameter of an IEEE real data type with decimal precision, as returned by the function PRECISION, of at least p digits and a decimal exponent range, as returned by the function RANGE, of at least r.

If no such kind type parameter is available on the processor, the result is as follows:

• -1 if the precision is not available
• -2 if the exponent range is not available
• -3 if neither the precision nor the exponent range is available
• -4 if one but not both of the precision and the exponent range is available.

If more than one kind type parameter value meets the criteria, the value returned is the one with the smallest decimal precision.

Example

IEEE_SELECTED_REAL_KIND (6, 70) = 8.
