Probably no reason, it should be fixed.

It's probably going to stay as well. The test routines have a common 
framework for working with arrays, but maybe that routine dates from way 
back, and wasn't ported to use it.

Both the assert_approx_equal and assert_almost_equal also have the 
built-in ugliness of specifying precision via decimals= which is somewhat 
clumsy for numerical work.
