OK - sorry for the noise... this is how to do it:
>>> N.nan_to_num( N.array([N.nan,N.inf,-N.inf],N.float32) )
[ 0.00000000e+00 3.40282347e+38 -3.40282347e+38]
In the meantime I noticed that there is a
N.asarray_chkfinite() function
but no equivalent for
N.asanyarray() !
Should N.asanyarray_chkfinite() be added !?
