Why would you write that out in QBASIC? In C++ all you have to do is type "sqrt".

His posts are proliferous and placed at EVERY QB site he has found!

Currently he is polluting the QB64 site also....... :(

(LOL) A post without your opinion, has less category.!

I think that my experiments are simple, useful.

Also some people are curious mathematical experiments.

:wink: In a way is good, both have many fans ...

The write post in QB64, is that QB64 will be a great dialect of Basic, It has a great future!!!!



Thanks for your opinion, but I only know Qbasic.

Basic also has SQR (x)

(I'm old school, also I'm very old)

The Germans say:

:wink: Why make things easier when you can make it with difficult!

No German EVER said that!

They may have said: "Hey this is a nice country, let's take it over!"

The wimpy French said: "Come right in..."

Note that the Germans never even wanted Spain because all they knew was QB.

I love those Europeans with their Euros.
