Tip Calculator

The Tip Calculator splits a restaurant or service bill across a group and computes the gratuity. It takes three inputs — a bill amount, a tip percentage, and a number of people to split by — and returns the tip dollar amount, the grand total, and the per-person share. The tip percentage is set with a slider from 0% to 50% in 1% steps, defaulting to 15%.

1. Enter the Bill amount (for example, 100) in the number field at the top. 2. Drag the Tip % slider to choose a gratuity from 0 to 50 (defaults to 15). 3. Enter the number of people in the Split field (minimum 1). 4. Press Calculate to compute Tip Amount, Total, and Per Person, each shown to two decimals in dollars.

Tip Amount = Bill × Tip% / 100. Total = Bill + Tip Amount. Per Person = Total / Split. All currency outputs use USD with two decimal places (toFixed(2)). The Split value is parsed as an integer; if it is invalid or zero, the code falls back to 1, so division by zero cannot occur.
