Manual
The questions which are considered here:
Mobcad usage
Basements
The first step is to create or load the saved
project. To do this you need to select menu item New in Main Menu.
The editor window will be opened. All calculations are divided into separate
equations. For example, 5+5=10 is equation and sin(pi/2)=1 is
an equation too. So, to make new equation press the button Menu in editor
window. In the next window select item Insert equation. You will automatically
return to the editor window where you'll see that the new input field has been
added. The form of writing is the same as in Mathcad. If you have any expierence
with Mathcad, you'll have no problems here.
For example, we need to calculate the problem 5+9.
So, enter 5+9 in the input field and press Call button. The result
will appear to the right: 5+9=14. You can also refresh the calculation
result with this button.
Functions creation
Lets us think that we want to create the function which will
calculate the addition result 2 of its parameters. To do this enter sum(a,b):=a+b,
where sum is the name of the function and the letters in brackets are its
parameters. To use this function you need to create one more equation below (!),
enter sum(6,8) and press the Call button. That's all! Easy, isn't
it? You've got the result sum(6,8)=14.
Variables creation
Variables creation has no difference with functions creation.
For example, let's create a variable which will be the square root result of 2.
To do this enter a:=sqrt(2) in the empty field and press Call button.
Variable a is ready to be used! To use this variable it is enough to type
it's name, for example a+2. The result will be a+2=3.414214
Setting the amount of decimal places
To set the amount of decimal places, select the required equation
and press the button More. In the opened window you'll see Decimals
field, enter there the amount of decimal places. Press the button Ok and
you'll be back to the editor's menu.
Convertion of numbers to any number system
To set the number system to which it is required to convert
the result, select the equation and press the button More. In the opened
window you'll see Radix field. Enter there the number system. For example,
2 is a binary system. Press the Ok button and you'll be back to
the editor's menu.
Mobcad supports 3 additional number systems that the
numbers can be entered in.
Suffixes:
h - hexadecimal
o - octadecimal
b - binary
To enter the number in the required form add the corresponding suffix to the end
of a number. ATTENTION ! If the first character in the number system is
the letter then this kind of number should be started with zero.
Example:
1000b = 8
10h = 16
0ffh = 255 (!)
10o = 8
Error report
If you entered invalid equation or the error has been occured
during calculation process, the equation field takes the red
color. To view the error details, select the required field and press
More. Error message will be at the top of the window.
Enum data type
Beginning from version 1.3 Mobcad Light supported enumerated
data type. For example: a:=1, 2 .. 10. So, a will be an array
with values from 1 to 10 with step 1. You may access separate elements specifying
the index of element in brackets after the name of variable. For example: a(4)
= 4. To view all elements press the button More.
Beginning from version 1.4 there is new way to define
Enum data type. The previous one is absolete. Now you must use either
Array(from, next, to) or Enum(n1, n2 ..
nn).
Mobcad particulars
- There is the system of visible ranges in Mobcad. What does it mean ? It
means that you can't use variable of function if you have not defined it before
your equation. Surely, it is not applied to system functions and variables,
such as sin, cos, log.
- You cannot redefine system functions and variables. For example, you can
write pi:=5, but, in spite of it, it's value will remain 3.14.
- You can use the numbers in the names of variables and functions, but the number can't be the first character in the name. The reason is revealed in
hexadecimal, octadecimal and binary number systems support .
- When the new equation field is creating, the number of decimal places and radix are taken from a previous equation.
Keymap
Colors
The colors which represent different equation's states:
- Red - the error has been occured.
- Yellow - the equation is in calculation queue.
- Green - the equation is being calculated at the moment.
- Blue - the equation is successfully processed.
- White - the equation that isn't taking place in calculations (comment).
