//Makes Button wait for a mouse click if button is click table_print is called

var round2;

Answer 1

몇 가지 오류

가있는 것 같습니다

먼저 round2라는 변수를 계산

round2 = interest_amount2.toFixed(2); 

,

다음 라운드의 값 표시 :

label_interest.text += String(round) + "r"; 

둘째, TOTAL_AMOUNT이 아닌 둥근 값의 합이며, 자체 반올림되지 않습니다

total_amount = interest_amount2 + a_amount; 

어쩌면 당신은 모든 숫자 값을 계산할 수를, 다음 예와 같이 반올림 된 값을 표시하십시오.

label_amount.text += a_amount.to_fixed() + "\r"; 

참고 : 숫자를 문자열로 변환 할 필요는 없습니다. 그것들을 String으로 연결할 때 암시 적으로 수행됩니다.
