[Scilab-users] linearly spaced vector

[Rafael Guera]

Hello,

The error magnitude seems to smaller than the default machine precision for Scilab double floating numbers (%eps = 2.220D-16) .

There are some Scilab packages for arbitrary precision (MPScilab, MPAT, Xnum,...), you may want to check them out.

Regards,
Rafael

Subject: [Scilab-users] linearly spaced vector

I expected the following script to generate　linearly spaced vectors x1,x2 and
x3 with step 0.01.
But x1(3),x2(2) and x3(15) are slightly different values from expected
values.
This phenomena happens with both Scila5.5.2 and Scilab 6.0.0 alpha.
Is there any ways to get exactly expected values?

********************
min=0.04;
low=0.098;
high=0.2;
x1=[ceil(low*100)/100:0.01:floor(high*100)/100]
disp(x1(3)-0.12);
x2=[floor(low*100)/100:0.01:high]
disp(x2(2)-0.1);
x3=[floor(min*100)/100:0.01:high]
disp(x3(15)-0.18);
******************
Best regards
