PHP Numbers

Integer & Float

$int = 42;             // Integer
$float = 3.14159;      // Float (double)

Type Juggling

PHP automatically converts between types:

$result = "10" + 5;    // 15 (string converted to int)

Math Functions

abs(-5);        // 5
round(3.7);     // 4
ceil(3.1);      // 4
floor(3.9);     // 3
max(1, 5, 3);   // 5
min(1, 5, 3);   // 1
rand(1, 10);    // Random number between 1-10
