Trouble with incorporating numbers into Titanium

I have a query about adding a decimal number to a latitude value obtained using forwardGeocoder. Here's the code snippet I am referring to:

Ti.Geolocation.forwardGeocoder(textField.value, function(e) {
            var a = e.latitude;
            var b = 0.1;
            var c = a+b;
            Ti.API.info('result c:  '+c);
});

The output displayed is:

[INFO] result c:  40.7145500.1

The issue here is that the provided number is not actually being added to the latitude value, but rather just concatenated as a string.

Interestingly, when I tried subtraction operations, it worked flawlessly. Similarly, using custom values for variables a and b also yielded accurate results.

Ti.Geolocation.forwardGeocoder(textField.value, function(e) {
            var a = 0.1;
            var b = 0.1;
            var c = a+b;
            Ti.API.info('result c:  '+c);
});

In this case, the output was:

[INFO] result c:  0.2

If anyone can provide insights on how to effectively add a number to the obtained latitude value, it would be greatly appreciated. Thank you for your assistance in advance.

Answer №1

It appears that the variable e.latitude is being treated as a string in this case, causing JavaScript to convert the Number to a string and concatenate them together.

To resolve this issue, consider using the following approach:

Ti.Geolocation.forwardGeocoder(textField.value, function(e) {
            var latitude = parseFloat(e.latitude);
            var increment = 0.1;
            var result = latitude + increment;
            Ti.API.info('The final result after adding: ' + result);
});
