long() (cast)

Converts a value to the long data type. Here is an example:

double d = 2.5;
long i = long(d); // i holds "2L", an long value

The value inside of the parentheses (long(...)) can be of any type. However, if it is not a numeric type (like double, char, etc.), you will get strange results.

See the long reference for details about the precision and limitations of long variables on the Maple.
