PHP calculates the integer part of the quotient

PHP You can use the following method to calculate the integer part of the quotient: use the floor() function to round down to the nearest integer. Use the rounding operator int to truncate the decimal part.

PHP calculates the integer part of the quotient

In PHP, you can use the floating point division operator/ to calculate the floating point part of the quotient part. However, if we only want the integer part of the quotient, we can use one of the following methods:

Method 1: Using the floor() function

$dividend = 10;
$divisor = 3;

$quotient = floor($dividend / $divisor);

echo $quotient; // 输出：3

floor() The function returns a floating point number rounded down to the nearest integer.

Method 2: Use the rounding operator int

$dividend = 10;
$divisor = 3;

$quotient = int($dividend / $divisor);

echo $quotient; // 输出：3

The rounding operator converts a floating point number to an integer, truncating the decimal part .

Practical case: Calculating the quantity of goods in an e-commerce order

Suppose we have an e-commerce order that contains the following data:

• Total amount of order: $100
• Price of each item: $20

We can use the integer part of the quotient to calculate the quantity of items in the order:

$totalAmount = 100;
$itemPrice = 20;

$quantity = int($totalAmount / $itemPrice);

echo $quantity; // 输出：5

In this example, $quantity will equal 5, indicating that the order contains 5 items.
