CS-MIC is a .NET library written in C# designed to give developers easy access to expression parsing. For many developers, there is no need to involve complicated settings and formats. With few exposed methods and objects, CS-MIC makes basic expression solving as simple as possible with as little logic required from developers as possible. In fact, one can pull a value with only one line of code.
CS-MIC is available as a package on nuget.org for ease and convenience. You can follow the instructions listed on the package site, or use the nuget package manager to search the nuget repository for cs-mic and install it from there.
CS-MIC follows a few basic rules when interpreting user input, but should prove to be fairly straightforward for most developers. While CS-MIC tries to ensure that the order of operations as far as it knows them (parentheses – powers, multiplication, division – addition, subtraction), there may be instances where formatting fails. If this should be noticed, please report it.
+ - Addition
– - Subtraction
* - Multiplication
/ - Division
^ - Raise to a power
% - Modulus
:: - Assign a numeric value to a variable.
:= - Assign an equation to a variable.
-> - Assigns a comma delimited array of numbers to an array variable.
== - Returns ‘True’ if two values are equal to each other.
> - Returns ‘True’ if a value is greater than another value.
< - Returns ‘True’ if a value is less than another value.
>= - Returns ‘True’ if a value is greater than or equal to another value.
<= - Returns ‘True’ if a value is greater than or equal to another value.
- Decimal
- All numbers are interpreted as decimal by default.
- Binary
- Binary numbers are succeeded by a B, non case sensative.
- Hexadecimal
- Hexadecimal numbers are preceded by 0x, non case sensative.

- Any valid expression can be computed.
- All computation counts towards the script’s history. This means that once a variable is set inside a script, the variable will remain set until execution of the script is complete.
- Only one command can be executed per line. No token is required to end the command.
- Every code block must be opened and closed with a bracket ( { } ). The only exception is the main code block.
while - Executes a code block as long as a given condition evaluates to true.
while(bool expression)
{
CODE BLOCK
}
for - After executing an initial condition, a code block is executed while a condition is met. A final statement is executed at the end of each iteration.
for(* expression, bool condition, * expression)
{
CODE BLOCK
}
if - Executes a code block if a given condition evaluates to true. An optional else block can follow the if block for execution if the statement evaluates as false.
if(bool expression)
{
CODE BLOCK
}
else
{
CODE BLOCK
}
echo - Displays the output from the proceding expression.
echo: expression
say - Displays a string.
say: “string”
display - Combines strings and expressions to a single line in the output stack.
display: “string”, 12 * 2, “string”, sin(12)
function - Creates a new function with a given name, and any number of expected arguments.
function(newFunction, anyArgumentName)
{
sin(anyArgumentName) + cos(anyArgumentName)
}
- Block Tokens
- Starting token: /*
- Ending token: */ *Any line falling between block comment tokens will be ignored by the macro builder at execution time.
- Line Tokens
- //
- Any line starting with the line token will be ignored by the macro builder at execution time.
- //
Example Script
say: “Fibonacci Sequence”
temp :: 1
y :: 1
echo: y
for(x :: 1, x < 11, x :: temp + y)
{
echo: x
temp :: y
y :: x
}
x :: 1
say: “While Loop”
while(x < 10)
{
if(x == 5)
{
display: “The condition ‘x == 5’ has been met. x = “, x, “.”
}
else
{
echo: sin(x)
}
x :: x + 1
}

The following is a list of the internally recognized functions in CS-MIC:
sin(double expression)
Returns the sine value of a given expression.
cos(double expression)
Returns the cosine value of a given expression.
tan(double expression)
Returns the tangent value of a given expression.
round(double expression)
Rounds an expression to the nearest whole number.
sqrt(double expression)
Returns the square root of an expression.
abs(double expression)
Returns the absolute value of a given expression.
exp(double expression)
Returns the constant e raised to a given power.
log(double expression1, double expression2)
Returns the log of expression1 to the base of expression2
precision(double expression1, int expression2)
Returns the value of expression1 to a given precision. For example, precision(12.3456789, 4) will return 12.3456.
