Description

Noncompliant code example

function automatic f(real r);
  shortreal s = r;
endfunction

Compliant solution

function automatic f(real r);
  shortreal s = shortreal'(r);
endfunction

A floating point value is implicitly converted to a narrower floating point type.

This is not necessarily wrong but make sure that it is really what was supposed to be implemented. If so, add an explicit cast.

Parameters

No parameters.
