Kotlin Custom Type Conversion FAQs

What is the difference between type conversion in Java and Kotlin?

In Java, type conversion is implicit, and we are allowed to convert only from more minor to more significant data types. On the other hand, Kotlin type conversion is explicit, and by using helper functions, we can convert variables from smaller to larger data types and from larger to smaller data types.

Which helper function do we use for type conversion related to the boolean data type?

Kotlin doesn’t support type conversion of boolean data type. Therefore, there is no helper function for boolean types.

Why is Double preferred for most calculations?

The precision of a floating-type data value shows the number of digits we can have after the decimal point. The precision of Float is just 6-7 decimal digits, whereas the precision for the double variable is about 15 digits. Hence, we prefer using Double for most calculations.
