Summary: repr and str return different results for a some floats

Details: I was getting some strange result when converting between strings
and floats for doing calculations and discovered that it was happening when
executing the following code.

def test_float( a_float ) :
	print a_float, str( a_float ), repr( a_float )
	
if __name__ == '__main__' :
	test_float( 0.01 )
	test_float( 0.02 )
	test_float( 0.03 )
	test_float( 0.04 )
	test_float( 0.05 )
	test_float( 0.06 )
	test_float( 0.07 )
