[Scilab-users] Rounding error or precision setting?

[Lester Anderson]

Hello,

Just a quick query. Not been using Scilab for a while, so maybe I have
missed something, but is there a built-in precision setting for working
with real and imaginary functions?

Tried the Euler formula (special case) in Scilab 5.4.1:

-->x=cos(%pi)+(%i*sin(%pi))
 x  =

  - 1. + 1.225D-16i

-->y=%e^(%i*%pi)
 y  =

  - 1. + 1.225D-16i

The real part is fine, but the complex has a measured value (approaching
zero). Is there a way to tell Scilab if this gets beyond a limit to round
off at zero say?

Sure this is an easy one!

Cheers

Lester
