Pi symbol vs “Pi number” (π vs 3.14) — quick clarification

Beginners often ask: “Do I type π or do I type 3.14?”

• π is the symbol used in formulas and maths writing.
• 3.14 (or more digits) is the approximation you use when you need a decimal number.

So if you’re writing a formula, you usually type π.
If you’re calculating, you might use 3.14 or a calculator’s π button.

“Alt code didn’t work”
