My guess is that you didn't try @skrishnamurthi suggestion: > Did you try the `sin(pi / 6)` example? You'll find that Pyret produces a rather interesting result that is also instructive. The result of this doesn't feel like magic and doesn't resemble "JavaScript's truthiness and type coersion" at all IMO. Here's a live code editor where you can try it out: https://code.pyret.org/editor https://code.pyret.org/editor I found it to be a very refreshing and intuitively-guiding experience :) --- Spoiler alert! So, fist i had to find how to access pi and sin(), which was simple enough googling for documentation. Typing `num-sin(PI / 6)` on he editor already gives an interesting result: ~0.49999999999999994 That ~ there looks suspicious! Then i tried `num-sin(PI / 6) == 1 / 2`, which seems to be syntactically invalid and yields an awesome error message: Reading this expression errored: num-sin(PI / 6) == 1 / 2 The == and / operations are at the same grouping level. Add parentheses to group the operations, and make the order of operations clear. Kudos to the Pyret team for such a nice error message! So finally, adding those missing parens, `num-sin(PI / 6) == (1 / 2)`, yields another informative and useful error message: Attempted to compare a Roughnum to an Exactnum for equality, which is not allowed: The left side was: ~0.49999999999999994 The right side was: 0.5 Consider using the within function to compare them instead. All in all, i'm very impressed with the clarity and approachability of the language. Thanks @skrishnamurthi for the suggestion of trying this out! :D
