BERLIN (Reuters) - German business morale hit a record high in July as "euphoric" manufacturers, shrugging off the impact of a strong euro, anticipated a surge in already robust exports from Europe's biggest economy. The Munich-based Ifo economic institute said on Tuesday its business climate index, based on a monthly survey of some 7,000 firms, hit its third record high in as many months with a rise to 116.0 from 115.2 in June.
