|Description:||Returns the base of the model representing numbers of the same type and kind parameters as the argument.|
|Class:||Inquiry function; Generic|
|Arguments:||X must be of type integer or real; it can be scalar or array valued.|
|Results:||The result is a scalar of type default integer. For an integer argument, the result has the value r (as defined in Section D.1). For a real argument, the result has the value b (as defined in Section D.2).|
If X is a REAL(4) value, RADIX (X) has the value 2.
