HI-TECH programming problem

[jameschia]

Wow!!!! You write it by yourself? Its so amazing!!!
So that means I still have a very very long journey to become a programmer.
By the way, some question here. How we going use those function?
For example if I wan to perform a calculation with equation
" x = y*sin(50) "
Then my code will be
float x = y * sine (50);

And at the cosine function, you add return 0 and the end of the function. Will that command return a zero value back to my main function and finally affect the calculation?

No the return is put there to stop a warning... The code should never reach that return... If it does there was an error.

Your example is correct.. The reason I changed the function name is... If I use cos(); instead of cosine(); I get a warning that there if a conflict, as cos(); is already defined..

The result is not perfect but for most applications it will do.

got it. i have tested the code and it work perfectly for my project.
thanks for your effort. ^^

Ok.... a few things to remember..... up to 90.0 degree.... ( you'll have to take care of 90 -180 - 270 - 360 ). But that's pretty simple...

arccos returns the angle to two decimal places..... there are a few instances where it's 0.01 out... (I use these routines on cranes so they work pretty well).

So we have... cosine(); sine(); arctan(); arccos(); and arcsin(); also we have abs();

HI,

How to download this file it is not downloading and opening in new tab, why??
