【Edabit 算法 ★☆☆☆☆☆】Return the Remainder from Two Numbers

math numbers

Instructions

There is a single operator in JavaScript, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value.

Examples

remainder(1, 3) // 1
remainder(3, 4) // 3
remainder(-9, 45) // -9
remainder(5, 5) // 0

Notes

• The tests only use positive and negative integers.
• Don’t forget to return the result.

Solutions

function remainder(x, y) {return x % y ;
}

TestCases

let Test = (function(){return {assertEquals:function(actual,expected){if(actual !== expected){let errorMsg = `actual is ${actual},${expected} is expected`;throw new Error(errorMsg);}}}
})();Test.assertEquals(remainder(7, 2), 1)
Test.assertEquals(remainder(3, 4), 3)
Test.assertEquals(remainder(-9, 45), -9)
Test.assertEquals(remainder(5, 5), 0)
