How to make the imaginary part of a +0. I zero globally? @Jonathan Shock Is there a way to confine all the numbers to real numbers in a program? Because I don't need imaginary number. |

How to make the imaginary part of a +0. I zero globally? @bills, what if I need to compare a to an integer like If[a>3,..,..], whereas a is actually a + 0.I? Then error occurs. |

How to make the imaginary part of a +0. I zero globally? Jonathan Shock: I don't know Chop fails outside the MatrixForm. But doesn't $Post = Chop[#, 10^-16] &; tells Mathematica to neglect digits smaller than 10^-16 automatically？ |

Is there a way to globally set when to treat a very small number as zero? Andy Ross ,Does $Post = Chop[#, 10^-13] &; really take away the digits smaller than 10^-13? I find that those digits still exist by Print[MatrixForm[FourierDCT[FourierDCT[{0, 0, 1, 0, 0}, 2], 3]]]; |

Can I put subscripted parameter values into a package? I found a way to use subscripted variables, that is transforming them into symbols first, then use symbol like q[UnderBracket]Subscript[UnderBracket]1 in the packages. |

Can I put subscripted parameter values into a package? @halirutan,I modified my question. I want to put all parameters (including subscripted ones) into a single package, then I call these data in the main program. |

Can I put subscripted parameter values into a package? Thanks, halirutan. a little problem arose when I am using subscripted variables. In my main program, I used Symbolize[ParsedBoxWrapper[SubscriptBox["", ""]]] to transform all subscripted variables into symbols, I find that I can not use the subscripted variables in the package any more. |

How can I draw a Cuboid given its center and its dimensions? Sorry about that, I did't realise that I had to vote that much. I voted for questions asked by others, does it have anything to do with my answers? |
