The order explicit by using newton / (centi meter).įor the same reasons, expressions like 500 gram / 20 gram and (500 gram) / (20 gram) yield different results.Īn important feature of SpeedCrunch’s unit system is dimensional checking. ‘newtons per centimeter’, don’t simply type newton / centi meter – this will be interpreted as (newton / centi) meter! Instead, make For instance, if you intend to express the unit Means that their use follows the same rules of precedence as any other mathematical operation. This limitation (or feature, depending on your point of view) In SpeedCrunch (unlike in textbook notation), prefixes can be used on their own. In that case, the imaginary part of these numbers is discarded when passing them as an argument to a built-in function. However, previously stored variables may still contain complex values. When complex numbers are disabled, the constant j is not available. However, when given a real argument, cbrt() will always return the real cubic root, regardless of whether or not complex numbers are enabled. With complex number support enabled, the power operation x^(1/3) will return the first complex cubic root of x which is usually non-real. Refer to a function’s documentation for more information.Ĭaution is advised when using functions like cbrt() or any fractional power operation with complex numbers. Not every function in SpeedCrunch supports complex arguments. Simply defining i=j allows you to use i as an alias for j. Although SpeedCrunch does not support this notation by default, it is added easily enough. Some users (especially mathematicians or physicists) may prefer to use the letter i for the imaginary unit. If necessary, consider writing the multiplication explicitly, i.e.

Microsoft Windows NT/2000/XP/Vista or Linux (32- and 64-bit) or Mac OS X 10.3/10.4/10.J ^ 2 = -1 ( 5 + 3 j ) / ( 8 - 2 j ) = 0.5+0.5jĪ note on the syntax of complex numbers: 5j denotes the number 5*j while j5 is a variable named ‘j5’.

#Speedcrunch online portable
To top it all off, SpeedCrunch works on Windows, Linux, Mac OX and comes in a portable version. There are also a few more features I did not talk about like the ability to save/load sessions, work in radians or decimals, etc. In addition to the already mentioned, SpeedCrunch supports up to 50 decimal places and is extremely keyboard friendly (you can type everything in and use shortcuts if you wish – never have to even touch your mouse).
So let me explain why SpeedCrunch is superior to Windows Calculator: For those that have never used a graphing calculator, my previous statement is probably meaningless.
The best way I can describe SpeedCrunch is to say SpeedCrunch is a graphing calculator while Windows Calculator is on the levels of a standard/scientific calculator. Well good thing there is an open source Windows Calculator replacement called SpeedCrunch (thx Liam!): One of my biggest grips with Windows Calculator is that you can’t see the computations you did before or the ones you are doing now. However it is an annoying piece of **** to use. Windows Calculator provides you with a fair amount of functionality in terms of mathematical computational needs.
