$ceil

Update records by setting the value of a numeric column to the smallest integer greater than or equal to its current value. The $ceil method is used to modify numeric fields by rounding up to the nearest whole number. This is useful when you need to ensure that the value is rounded up, even if it’s already a whole number or a fraction.

await Member.$update({
    $where: { 
        age: { 
            $eq: 16 
        } 
    },
    $update: {
        $ceil: {
          age: 1
        }
    }
});
