Example

fdef square : number

Features

• Basic math operations (See quirks)
• If statements
• Function return types
• Functions
• Comparisons between numbers
• Signed / unsigned integers, floating point numbers
• Strings (They don't serve any purpose for now)
• Comments
• Simple stack operations (drop, dup)

Quirks

• Any math operation on any integer type result is a f64:

# Output: 4.0 #
2 2 +

TODO

• Including files
• Don't coerce all numbers to f64 after any math operation
• More stack operations
• Reading from files
• Arrays
• Escaped strings
