Currently, my goal is to add two numbers from an array using the code below. However, instead of adding them together, it seems that the code is only concatenating them.
if (this.id == "=") {
if (HYUTS[1] == '+') {
var sum = HYUTS[0] + HYUTS[2];
alert(sum);
}
}
if (this.id == "=") {
if (HYUTS[1] == '-') {
var difference = +HYUTS[0] - +HYUTS[2];
alert(difference);
}
}
This indicates that the values in HYUTS[0] and HYUTS[2] are stored as strings rather than integers, use the expression +HYUTS[0] to convert them into integers.
Utilize the Number method when dealing with string values within an array
if (this.id == "=") {
if (HYUTS[1] == '-') {
var difference = Number(HYUTS[0]) - Number(HYUTS[2]);
alert(difference);
}
}
