![]() The T variable is used to create animated or time plots. Graph multiple functions by separating each equation with a comma. For example, "z=x+y" is just entered as "x+y". Plot 3D functions by using the x and y variables. For example, "r=2?" is just entered as "2?". Plot polar equations using the ? variable. For example, "y=sin(x)" is just entered as "sin(x)". When you use the x, y and ? variables in an equation the answer will say Touch to Plot. Plot graphs with a single touch! Solve plots 2D and 3D functions using the x, y and ? variables. Multiply numbers, calculate a tip and find a square root all without clearing your results! Solve has four tabs that select four different calculators each with its own color. Simply touch the answer to store it and touch the stored answer to use it in an expression. 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. Use parentheses and trigonometry when defining variables.Īndroid's #1 Scientific Calculator. Define as many programmable keys as you like. Work with variables and generate "speaking" calculations. Put calculations side by side for comparison. Scratchpad for every-day calculations is being saved automatically. CalcTape for Windows requires Windows XP, Windows Vista (x86 and 圆4) or Windows 7 (x86 and 圆4).Įxtended functionality of the Pro and Enterprise version: CalcTape masters the four basic arithmetical operations, exponentials, and percentage calculations. Do similar calculations and play different scenarios. Use your existing CalcTape files as templates. CalcTape will refresh the whole calculation automatically again and again. Open the files later and you can change the calculations. Comment your calculation terms, to give sense and context to it. Use intermediate results to check and structure your calculation. Change any term afterwards and CalcTape will refresh the whole calculation automatically. Enter many calculation terms in one turn and still keep an overview - like on an adding machine. CalcTape makes the arithmetic process visible - you can generate intermediate results and subsequently correct or change all numbers and operations. With CalcTape, also extensive calculations remain clearly structured. CalcTape is a revolutionary new kind of pocket calculator.
