This update explains results without a value, makes large numbers easier to read and fixes a number of smaller things. New in version 2026.2.1: - When a calculation has no value, PocketCAS now says why instead of showing [ ] or undef: No real solution, No solution found, Undefined, Diverges, No limit or Unknown function, with a short reason below. A suggestion offers the next step, such as the complex solutions, the limits from the left and right, or a plot. - PocketCAS marks a typing error in the input, and a suggestion offers the fix: sin x becomes sin(x), and intergrate becomes integrate. A stopped calculation shows how long it ran and offers Calculate Again. - Next to an exact result, the ≈ line now also shows the decimal value of a result with units and of an integral without an exact value. Very large and very small numbers read as 2.43 × 10¹⁸ instead of 2.43E+18. - When rounding changed a decimal result, the suggestion Exactly shows the exact value. - Results and inputs show large numbers in groups of three digits, such as 1 234 567. Settings > Digit Grouping offers another separator, or none. The editor and copied text keep plain digits, and a number too long for the screen continues on the next line. - The Extrema suggestion now finds minima that it missed before, such as the one of abs(x) at 0. - Clearer calculation steps for some integrals and for extrema, and a step that is too wide for the screen continues on the next line. - On iOS 26, the titles of What's New and the welcome pages are no longer cut off at the top. - On an iPhone in landscape, the Tools menu shows all its tools without scrolling. - Plot Settings show a swatch next to each color, and a color that is not in the list appears as Custom Color. - VoiceOver reads ( and ) as parentheses instead of braces, and selecting entries in Select mode works as expected. - Clearer German and French texts, and a suggestion now adds just its calculation, without a comment line above it. - The previous version of PocketCAS still opens your documents. It shows the new reasons as plain text next to the result. Changes from version 2026.1: - Suggestions under your results: the derivative, zeros, extrema and more, with the answers already shown. Tap one to add it to your document. Settings > Suggestions turns them off or shows them only under the newest result. - A small plot appears next to a function's result. Tap it to add the plot. - Calculation steps show how PocketCAS works out derivatives, integrals and a few other calculations. - Results look like a math textbook, and long results wrap to the width of the screen. - Clearer 2D plots with a finer grid, and 3D surfaces with soft light, shading and a floor grid. Plots in a document pan, turn and zoom right where they are. - Vector field plots: enter [f(x,y), g(x,y)] in a plot. - A new keyboard look, with your recent functions right above it. - On iOS 26 and later, PocketCAS uses Apple's new design, Liquid Glass, and has a new icon. - Brackets close by themselves, and printed documents break long lines at the page's width. - Plots now use seven curve colors, so a 7th or later curve in an older document may get a new color.
