How This Calculator Works

\n

This calculator uses the JavaScript modulo operator (%) to find the remainder after division. For example, to find the number of quarters in change, we use:

\n

quarters = Math.floor(changeAmount / 0.25);

\n

And to find the remaining amount after taking out the quarters, we use:

\n

changeAmount = changeAmount % 0.25;

Understanding the Logic

\n

The core of this calculator relies on two fundamental mathematical operations that are essential in programming:

\n

\n
1. Division: Used to determine how many times a smaller value fits into a larger one.

\n

2. Modulo (%): Used to find the remainder after division, which is crucial for calculating exact change.

For example, if the change due is $1.35:

\n

\n
• Quarters: $1.35 divided by $0.25 is 5 with a remainder.

\n

• Modulo: $1.35 modulo $0
