Also, > how does one convert from integer to real? Thank you. The fortran INT is equivalent to Floor The fortran NINT is equivalent to Round To convert from integer to real, use N[]. For example, N[3] = 3. The one exception is 0, since N[0]=0. This is because Mathematica treats simplification with an exact zero differently than with an inexact 0 (0.) If you use combinations of integers and reals in an expression, generally the integers will be converted automatically to reals. -- Rob Knapp Wolfram Research, Inc. http://www.wri.com/~rknapp
