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 !? -Sebastian ------------------------------------------------------------------------- Using Tomcat but need to do more?
