Integer is like a whole number without fraction: 2, 256, 2048.
Integer 就像一个没有分数的整数：2, 256, 2048。

Numeric is any number including floating point numbers: 2.478, +0123.45e6
数字是任何数字，包括浮点数： 2.478, +0123.45e6

According to the Laravel's Source Code, both the validations have the following logic.
根据 Laravel 的源代码，这两个验证都有以下逻辑。
// For rule 'integer'
protected function validateInteger($attribute, $value)
{
return filter_var($value, FILTER_VALIDATE_INT) !== false;
}
// For rule 'numeric'
protected function validateNumeric($attribute, $value)
{
return is_numeric($value);
}
