Round off issue with Double Values having more than 15 digits

I have a User Input field mapped to a property of type Double.

When the user enters a double with 15 integers and more than 2 decimals, anything after the 2 decimals tends to be omitted.

Similarly, if the value is 14 integers and more than 3 decimals, anything after the 3 decimals is getting omitted.

And PRPC starts rounding off numbers with more than 15 digits.

Is there a way to control the rounding off strategy?

Either use the Decimal type or store the value as a String.

Loss of accuracy when converting to/from double/String is a common occurrence and source of bugs in Java.

Maintaining data accuracy is significantly more important than programming/programmer convenience.

Are you actually using the value to do Math?

If so, in how many situations?
