isnum(1)

🌸 NAME 🌸

isnum — bestie, she just tells you if your string is a number or not, and what kind 💅

✨ SYNOPSIS ✨

isnum string

💖 DESCRIPTION 💖

Okay so isnum is the little utility that looks at your input string and is like "mmhm, I see you 👀" and then classifies it. She hands back an integer code based on how she IDs the input number, and here's the whole tea, no cap:

• 0 — string is not any sort of number, sorry bestie, it's giving "not math" 😭
• 1 — String is an integer 💯
• 2 — String is a floating point number 🦋
• 3 — String is a hh:mm:ss.ss time ⏰
• 4 — String is a yyyy-mm-dd date 📅

That's literally it. She identifies and classifies, and she does it in one neat little exit code. Iconic behavior, honestly.
