Hello,

I've been doing some Basic coding on the Prizm, successfully porting some programs from TI calcs and writing some of my own. I'm trying to find out some way to work around some instructions, so I have questions for the gurus:

-Any ideas on how to go about programming the "angle" instruction from TI on an equivalent for the Prizm? Example: Y=cos angle(0,2*pi*F*L)
-Any way to get a complex number in a variable? In TI calcs you can have "A=(R1,2*pi*F*L)"
-Any other suggestions on how to work with complex number notation in a program?

Also, which is the fastest way to plot dots in a Prizm? I noticed the "IF-then" instructions are very slow, as well as the loops, or is this a limitation of the built in BASIC?

Thanks

you can use Arg function instead

-Any way to get a complex number in a variable? In TI calcs you can have "A=(R1,2*pi*F*L)"

it's easy for example 1+2i->A

Any other suggestions on how to work with complex number notation in a program?

some function for work with complex number
Rep extract real part
Imp extract imaginary part
Abs compute absolute value(r=(x^2+y^2)^0.5)
Arg compute angle(theta=tan^-1(y/x)) result is always between pi & -pi
Conj compute conjugate of complex number( 2+i->A Conj A=2-i)

Also, which is the fastest way to plot dots in a Prizm? I noticed the "IF-then" instructions are very slow, as well as the loops, or is this a limitation of the builot in BASIC?

what??? you do'nt need use If Then.
you can use:
Plot x,y display pointer at the location specified by the coordinates and plot a point there
Line connect two plotted points with a line
& so on

Thank you for all the input! I'm off to test these in my code. Have a Happy New Year!
