Why `Double` for file size?

[ntalbs]

The size of File is represented by int:

ood-interview/file_search/filesearch/filesystem/File.java

Line 11 in 29b9ddc

private final int size;

But in LessThanOperator and GreaterThanOperator convert the values to Double.

ood-interview/file_search/filesearch/operator/GreaterThanOperator.java

Line 7 in 29b9ddc

return Double.compare(attributeValue.doubleValue(), expectedValue.doubleValue()) > 0;

ood-interview/file_search/filesearch/operator/LessThanOperator.java

Line 7 in 29b9ddc

return Double.compare(attributeValue.doubleValue(), expectedValue.doubleValue()) < 0;

Why not just use Number.intValue() and Integer.compare()? Ideally, those should be long in my opinion, as the file size is represented as long in java.io.File class.
