Basics

Datatypes:

Quick 4:

• Int/Float/Real/Complex 8/32/64
• Same as above but “Big” with Arbitrary Precision
• String is different than Char

NOTE:

• There are NO “:” like python
• Every block (function/if-else/etc) MUST have and end keyword
• ! after a function, means that fucntions is editing the given variable
• Array are stored in Column major aka fortran style format; accessing them is same, each row of given column is displayed first.
• Array index start at 1
• For element-wise operation use . dot=operator with + - / and functions as well such as sin.().

Determine type

typeof()

String functions:

Essentially its a container of chars.

Concatenate any number of strings

a * b

if-else

if (x > 0) && (y > 0)
   println("x AND Y is positive")
elseif (x < 0) || (y <0)
   println("x OR y is NEG")
else
   println("x is NOT positive")
end

• SHORTCIRCUITING : If multiple if-else statements are true, it will just execute the first one and exit the block.

Ternary Operator:

x <conditional operation> ? <TRUE clause> : <FALSE clause>
x > 0 ? println("is POS") : println("not positive")
