![]() Solve is a calculator like no other! Solve solves expressions as you type and features an innovative memory system to store and recall answers. Please read the help for more information. If you don't need these modes, please make sure that 'Enable Radix Modes' is disabled in the settings. Press DEC to return to decimal operation. * If any of the digit keys are disabled, or the decimal point doesn't work, or you have answers with letters in, or basic arithmetic appears to be wrong, then you are in binary, octal or hexadecimal mode. Degrees, radians and grads are supported, indicated by DEG, RAD, GRAD in the display. * If sin/cos/tan functions don't give the answer you are expecting, make sure you are in the correct angle mode. * If the percent key appears to give wrong answers, make sure you are pressing '=' at the end, e.g. * If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc - see en./wiki/Kibibyte. If you find RealCalc useful, please consider purchasing RealCalc Plus to support further development. ![]() * Degrees/minutes/seconds calculations and conversion * Fraction calculations and conversion to/from decimal RealCalc Plus contains all these features, plus: * Configurable digit grouping and decimal point * Scientific, engineering and fixed-point display modes * Trig functions in degrees, radians or grads RealCalc includes the following features: ![]() See elsewhere on this page for the link, or select 'Upgrade' from the RealCalc menu. Looking for fractions? Degrees/minutes/seconds? Landscape mode? You need RealCalc Plus. A fully featured scientific calculator which looks and operates like the real thing. You could do this with several variants, including desktop style types like VirtualBox or the server style approach with Xen or KVM (see this Ubuntu guide).Android's #1 Scientific Calculator. Using virtualization is a lot more involved, as you have to maintain several copies of your complete operating system and install the variants of the software on each of them. When doing this right, you can start your software variants from their respective directories. Which would then put the compiled binaries into /opt/yoursoft/var1/bin or something similar.ĭependent on what makes a complete build of your software, you might need complete lib, etc, bin etc. Something like -prefix /opt/yoursoft/var1 ![]() configure to create installation prefixes for your various versions. In a general case though, what I would first try to do is to check if you can use. It's impossible to tell what might be the best way to achieve your goal, as this is very much dependent on the software you want to use and the flexibility of it's built environment. Is this practically possible to achieve? I would highly appreciate a detailed response with possible URLs. However, I don't know how many users would login at any given time. So, user John's Apache is transparent from user Adam's, although both Apache are being executed on the same physical server. To illustrate this, consider multiple users telnet-ing to a Linux machine, compiling multiple instances of Apache, and running them. Moreover, these installations would not be done "statically". ![]() Essentially, this means having multiple instances of the same software running, but each of them have been installed with different configurations. While in the other case I might exclude that file and include some other file. Is it possible to "virtualize" this software so that different installations of the software could be done (with different options) and used?įor example, in one instance I might wish to use in Makefile and compile. I've a software, which is to be installed from it's source code using. ![]()
