Soulver modulus5/21/2023 ![]() ![]() As you type on the left side of a document, Soulver keeps track of the math on the right-hand side with syntax highlighting that makes the calculations simple to follow. Writing calculations in plain English is faster than using a spreadsheet too because you don’t have to stop to consider what formulas to apply to which cells.īest of all, Soulver approximates how you’d solve the same problems with a pen and paper, making it intuitive, but also better because the calculator is built right into the page. Instead of guessing what all the numbers on a page mean, you can give each a descriptive label and add other text providing context. By mixing text and figures, a Soulver document becomes a roadmap making it easy to retrace your steps when you revisit your work later. The Mac and the iOS apps are part text editor, part calculator and work the way you think by letting you combine text and numbers on the same page.įor anyone who spends more time in a text editor than a spreadsheet app, Soulver is perfect. If you’ve ever sat down with a pen and piece of paper to work out calculations, you’ll understand the power of Soulver immediately. Both changes will be problematic for some users who may want to wait for future updates that the app’s developer has said are in the works. ![]() Soulver also saves its data as a single ‘sheetbook’ file now, which means it can no longer save or manage sheets as individual files saved to arbitrary locations on your Mac. However, unlike its predecessor, version 3‘s file format is incompatible with the iOS version of the app and earlier Mac versions. The app has never been easier to use, and its implementation of a sidebar to corral sheets is fantastic. Soulver 3 for Mac features an updated design and substantial new functionality that I love. By combining elements of a text editor, spreadsheet, and plain English syntax, Soulver commits those easily-lost notebook scribblings to a format that allows for greater experimentation and easier sharing.ĭuring WWDC last week, Acqualia Software released a major update to the app. It’s the kind of math that happens in notebooks and on the back of envelopes. However, day-to-day life requires calculations that don’t demand that level of horsepower and benefit from contextualizing numbers with text. Full-fledged spreadsheet apps like Numbers and Excel have their place. Further ReadingĮxplore modular arithmetic and modulo operations further including a mod b for negative numbers.The strength of Soulver lies in its flexibility. Similarly, 5 mod 10 = 5 since 10 divides into 5 zero times with 5 left over as the remainder.įor positive numbers, whenever the divisor (modulus) is greater than the dividend, the remainder is the same as the dividend. Example: 1 mod 2ġ mod 2 is a situation where the divisor, 2, is larger than the dividend, 1, so the remainder you get is equal to the dividend, 1.įor 1 divided by 2, 2 goes into 1 zero times with a remainder of 1. In some calculators and computer programming languages a % b is the same as a mod b is the same as a modulo b where % or mod are used as the modulo operators. 226 mod 4 = 2, so no, 226 is not a multiple of 4. Is 226 a multiple of 4? Divide 226 by 4, so 226 / 4 = 56 with a remainder of 2. In terms of mod, 496 mod 4 = 0, so yes, 496 is a multiple of 4. You would divide 496 by 4, so 496 / 4 = 124 with no remainder. For example you would have to calculate "is 496 a multiple of 4?". If you did not use the mod operator you would have to do the math in your code. If x mod 4 = 0 then x is a multiple of 4.The logic for this part of your program would be: If the result is 0 the number is a multiple of 4 otherwise the number is not a multiple of 4. So you would create the logic to take an input and use the mod 4 operation on it. If a number is a multiple of 4, when you divide it by 4 the remainder will be 0. You can use the modulo calculation to accomplish this. You need to write a piece of software that tells a user whether a number they input is a multiple of 4. If you needed to find 27 mod 6, divide 27 by 6. To do this by hand just divide two numbers and note the remainder. ![]() The modulo operation finds the remainder of a divided by b. The modulo operation finds the remainder, so if you were dividing a by b and there was a remainder of n, you would say a mod b = n. Calculate a mod b which, for positive numbers, is the remainder of a divided by b in a division problem.
