Forcing numbers to be real.
Hi, I've not used Mathematica much, but I know there is a way documented of forcing Mathematica to consider a number to be real, so having an imaginary part of 0. Can anyone tell me how to do it - I can't seem to find it in the docs, although I know it is there somewhere. -- Dr. David Kirkby Ph.D, email: REMOOVE_THIS_drkirkby at AND_THIS_ntlworld.com former email address: davek at DELLETE_THIS_medphys.ucl.ac.uk web page: http://www.david-kirkby.co.uk Amateur radio callsign: G8WRB
