Converter-Calculator vs Logic-Gate-Design Pro Usage & Stats

This app is a bundle of 10 great Converter & Calculator apps for one low price & more are under development: •Units Converter with over 1700 units in over 50 categories •Currency Converter with over 160 currencies •Hex-Decimal-Binary Converter •IEEE754 Floating Point Converter •Roman Numeral Converter •Drill Bit Conveter •Simple 4-Function Calculator •Scientific Converter with up to 38 digits of precision •Amortization Calculator •A Collection of Reference Charts & Documents Originally introduced in 2010 under the name of iGotCharts, this app originally contained a collection of reference charts and a modest units converter. However, it has grown to so much more since its introduction so we have changed its name to be more reflective of its full capabilities. ConvertCalc was designed and developed by a professional engineer with over 45 years of metrology experience which is reflected in the features, capabilities, and accuracy of this app. It also has a very simple and attractive user interface. You can easily disable units & charts you don't need and put them in whatever order best suits you, then save it as a favorite and quickly switch between your favorites and the app defaults. There is also a powerful search feature to simplify locating a unit of interest, regardless of category. ConvertCalc is ideal for use in the kitchen as well as for engineering, surveying & scientific applications and anything in-between. Our conversion factors are consistent with NIST publications as well as other standards agencies and organizations such as API, BIPM, IAU, IEEE, IEC, etc. Every unit is defined & described. Whimsical units & systems such as smoots, FFF (furlong-firkin-fortnight) units and the Potrzebie System of units are also included for academic usage. ConvertCalc uses 64-bit floating point math with a 52-bit significand, good for 15 significant digits of data presentation. We have developed advanced algorithms and proprietary conversion factors to maximize the computation accuracy. Where NIST or other agencies define an exact relationship between two units of measure, ConvertCalc will perform those calculations precisely without any rounding. Inexact conversions may have slight rounding in the 14th or 15th digit, which still provides at least 13 significant digits of accuracy. It also includes a Hex-Decimal-Binary Converter with IEEE754 floating point notation capability and a Roman Numeral Converter. It also includes a Simple, Scientific and Amortization Calculator. The Scientific Calculator utilizes 64-bit base-10 decimal math providing 38 digit results. General App Features: • Retina support for both iPad and iPhone • All orientations supported for all devices • Swipe gestures simplify navigation and minimize button clutter • Save favorites in any chart or unit category • Quickly alphabetize or enable/disable all items in a category • Reference charts and publications on a variety of topics • Currency converter with over 160 currencies • Extremely flexible units converter • Definitions & descriptions of every chart and unit • Print charts to Airprint printers • Email feedback or charts from within the app Units & Currency Converter Features: • Enter & convert data in decimal, scientific, or fractional numbers • Supports compound units (ft-in, st-lb-oz, hr-min-sec, etc.) • Quickly & easily adjust output mode & display precision • 64-bit math provides up to 15 significant digit conversions • Use thumbwheel picker or tabular list to view conversions • Indexed list of all individual units with powerful search feature • Attractive graphics help identify the units • Swipe up to update currency conversion rates • Tap the equal sign to quickly swap the from/to units • Tap the unit abbreviations for a description of that unit We welcome your suggestions for additional units, charts, or other features. .

Logic-Gate-Design Pro

The LogicGateDesign is a feature rich app designed by an engineer. This app allows the creative smart people like you to design, draw, analyse and simplify logic gate networks. You can draw logic gate networks and share it with others. You can generate truth table and find simplified/minimized boolean expression that represents the network. You can optimize and reverse engineer a boolean expression to draw a ladder logic diagram. It performs both forward engineering (boolean expression to logic circuit) and reverse engineering (logic circuit to boolean expression). There can be multiple groups of network and each group can have multiple outputs. Truth table is generated for all the outputs. You can simplify a boolean expression, and find the truth table and share it. Show truth table along with different types of boolean expression (simplified, Sum-of-products, Product-of-sums) The simplified expressions also gives you the number of gates required. You also get the alternate expressions for the same output with the gates required for that. You can generate a truth table, simplified boolean expression using input-output waveforms. You can generate a output waveforms, simplified boolean expression using truth table and input waveforms. You can generate a grey codes and grey code encoder wheel and share it. Do you have a truth table for your network and want to find the simplified/minimized boolean expression? This app has you covered. You can simulate your network by changing one input at a time or toggeling all inputs at once. This app generates beautiful diagrams (logic gate diagram or waveform diagram) that you can share with others or save it locally. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. There is also a page to help you study. This study tab teaches you some very important boolean algebra theorems. This is a perfect app for a creative smart individual like you. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
