Conditional notation is a way to specify a specific condition for Lagmite. In this case, it is denoted with <<>> and is highlighted orange. The notation format uses simple unknowns (#) or using the variables that are stated. Usually, this notation is used for the gen function. As an example, to generate the first 10 even numbers and squared, you can use the syntax:

disp [list] (gen [expr] #^2 <<calc [expr] #%2 == [expr] 0>> {1,10})

//Expected output: [4,16,36,64,100]

Basics

The operators that are used are:

• ≥ and ≤ which stand for less/more than or equal to.
• == which stands for equality.
• % operator for modulo.
• and and or as logical operators.

Most conditional notation formats follow the examples below:

• Odd and even numbers are denoted with <<<variable>%2==1>> and <<<variable>%2==0>>
• A number when added by 3 should be less than or equal to 4. <<<variable>+3≥4>>
• A number when subtracted by 20 should be more than 21 and is a multiple of 3. <<<variable>-20>21 and <variable>%3==0>>

Complex Logic

As an example, to show the word “math” when 1+6=7, we can use the syntax below:

disp [text] (calc [expr] 1+6)
disp [text] math <<[expr] ~== [expr] 7>>

//Expected output: math

Here, we utilized a simple known (~) to compare its value to 7, in which returns true, so it displays “math”.
