  • Excelente alternativa para reemplazar a Mathcad, me ha ayudado mucho en mi carrera de Ingeniaría Civil, me suscribí al plan anual, gracias.

    by Cristian Yamid Pérez Peña

  • As a Civil Engineering professor, I've realized to be hard to find a software suitable for both introductory and advanced subjects. SMath is the only free software I know to get the job done. Try it out.

    by João Felipe Melo

  • I'm absolutely love this app. It's a great tool for usual engineering calculations, and way more easier to use for me than matlab and others.

    by Zoltán Balázs

  • luce muy bueno el programa, demasiado útil, una potente herramienta de calculo de uso libre

    by IVAN KALLATA

  • Probably the best free math program out there. As an electrical engineer, you can do so many calculations, e.g for designig drive systems and calculate protection settings, can be almost entirely automated using SMath Studio. With the huge amount of plugins you can push SMath in an high level. Thanks a lot!

    by Karsten

  • The most important daily-use software for engineers. Far more powerful than actual Mathcad Prime. I actually use more SMath Studio than MS Excel at work. Thank you, Andrey, for this GEM.

    by Alvaro Gavilán Rojas

  • ein absolutes Muß für Ingenieure und Naturwissenschaftler und die, die es noch werden wollen. Ein perfektes Tool für Hochschulen aller Art. an absolute must for engineers and natural scientists and those who want to become one. A perfect tool for universities of all kinds.

    by Stephan Gottlieb

  • Congratulations!! This software is amazing!! An almost complete substitution for Mathcad!!

I had hoped for round-half-to-even instead of away from zero.
  • This is IEEE 754 default rounding mode
  • It is most common in engineering
  • It is the way I teach my students


What is the motivation of the design decision of rounding half away from zero?

The step-in feature without breakpoints is great.
This is a major step towards a very convenient context-inspector.

IMHO these features could be useful:
- Context display at cursor location (what you would see if there was a breakpoint there), perhaps some execute-to-cursor button
- Reliable call-outs for dynamic formatted display of the context items (currently, sometimes the callout doesn't show up)

Martin, I'm recieving many e-mails regarding "rounding is unpredictable".
Personally I do not see significant benefits from round-half-to-even (because SMath Studio never knows source of the data it works with), but this, of course, has no sence.

The benefit is that if summing up large numbers of rounded numbers then you don't get a systematic bias.
In round away from zero this is true only if the distribution of the numbers is symmetric to zero.

Maxima implements round to even.

As the type of rounding seems to be a matter of taste I would recommend to make this a settings item, at least for result formatting. For explicit rounding one could have separate functions or an optional argument.

====================================
Well, there is "rounding & rounding" ... most interesting:
http://mathworld.wolfram.com/RoundoffError.html

Nothing is absolutely true in this world.
1. NO math computations are true.
2. NO measurements are true.
3. NOT all minutes have 60 seconds ... What !

Yes "What" ... once in a while there is a Savant Lab [in Paris]
that adjusts the universal time ± 1 second.
I can survive the conventional ½ way up/down.

Cheers ... Jean.

Updated, thank you! Good
If you like my plugins consider to support SMath Studio buying a plan; to offer me a coffee: paypal.me/dcprojects
