[Classification]

[Syntax]

[Return value]

[Description]

This function obtains the absolute value of j (size of j), | j |. If j is a negative number, the result is the reversal of j. If j is not negative, the result is j. This function is the same as abs, but uses long type instead of int type, and the return value is also of long type.
