Description
            The goal of this toolbox is to provide a double-double implementation in 
Scilab.
These floating point numbers have a greater precision (but not a greater range)

that doubles.

This module allows to run the following script:

z1 = dbldbl_new ( 2 )
z2 = dbldbl_new ( 2 )
z1 + z2
z1 * 3
3 * z1
z1 / 3

We can add, subtract, multiply, dividy, compare double-doubles.
We can also compute elementary functions: abs, sin, cos, tan, asin, acos, atan,
exp, log, sqrt and power.

This is a Scilab port of David H. Bailey's ddfun90.f.
