double() (cast)

Converts a value to the double floating point data type. Here is an example:

int x = 2;
double d = double(x);  // d now holds 2.0, a double value

The value x can be of any type. However, if x is not a number (like an int or long long), you will get strange results.

See the double reference for details about the precision and limitations of double values on the Maple.
