JavaScript Math Operations

Math Object

Math.max(5, 10, 3);      // 10
Math.min(5, 10, 3);      // 3
Math.round(4.7);         // 5
Math.floor(4.7);         // 4
Math.ceil(4.2);          // 5
Math.random();           // 0 to 1
Math.abs(-5);            // 5
Math.sqrt(16);           // 4

Random Numbers

Math.random();                    // 0 to 1
Math.floor(Math.random() * 10);   // 0 to 9
Math.floor(Math.random() * 100) + 1; // 1 to 100

Key Takeaway

Math object provides mathematical functions. Use for calculations, rounding, random numbers. Essential for any numeric operations.
