LESSON 2.9

Exact Decimals and Binary Floating-Point

Zirk Decimal values are exact by default. Add the f suffix to use binary floating-point, which can introduce familiar rounding errors.

Goal Predict what the program prints.

Write a Zirk program, then run it to see the world react.

Predict the program output true true true false false false
