Converting from float to double is a widening conversion
Question
Converting from float to double is a widening conversion
Solution
Yes, converting from float to double is indeed a widening conversion. This is because a double data type is 2 times larger than a float. A float is a 32 bit IEEE 754 floating point, while a double is a 64 bit IEEE 754 floating point. This means that a double can accommodate 15 to 17 decimal digits of precision, which is more than the 6 to 9 decimal digits of precision for a float. Therefore, converting from float to double does not result in a loss of data.
