In C, a/b represents the quotient of a divided by b, and the result is a floating point number. If a and b are both integers, round down. The result type is determined by the operand types: a/b is of type int, float, or double, depending on the types of a and b.
The meaning of a/b in C

Details
Type rules
The result type of a/b is determined by the type of the operand:
Example
<code class="cpp">int a = 10, b = 2; float c = a / b; // c 为 5.0(向下取整)</code>
Note
In some cases, using floating point operations may produce rounding Enter error. Therefore, if exact integer division is required, it is better to use the modulo operator (%).
<code class="cpp">int remainder = a % b; // 0</code>
