iCalcline vs Renamer

iCalcline is a modern algebra calculator for iOS It can solve math expression with any level of parenthesis and functions You can use algebraic expression with numeric values and or variables constant names You can use in expression the variables and constants you created in the internal tables: 'alpha=bravo+K_1' (bravo will be taken from the variable table, K_1 from the const table and alpha will be assigned or created in the variable table) You can create, manipulate, delete and use how many variables you like inside the app. The internal iOS keyboard provides helpers to insert available functions, variables, constants, operators. Result is displayed immediatly. KEY POINTS • Evaluates mathematical expressions with parentheses, nested functions, variables and constants • Easy to use • The user simply inserts an expression and iCalcline displays the result • Variable creation and reference inside expressions are very easy using an interactive list. FEATURES • Algebra made easy and simple • Manages any nested level of parentheses using the correct precedence • Check your expression syntax in advance signaling errors • Can use an internal variable and constant table with editable values • You can manages unlimited numbers of variables and constant you like in the internal tables. • You can use in expression the variables and constants you created in the internal tables: 'alpha=bravo+K_1' (bravo will be taken from the variable table, K_1 from the const table and alpha will be assigned or created in the variable table) • Customized keyboard with Functions, variables table, constants table and frequent used symbols available to insert with a single touch • Can change on the fly calculation precision (up to 9 decimals thanks to use of long double calculation) • Variable font sizes • Select a variable or a value and inserting a function will wrap it inside the function parenthesys • Uses decimal and group separator in accordance with your local settings • Full log of executed calculations • Optional step by step solving showing all the mathematical passages in the log. • Retains values over successive re-launch • DEG° and RAD calculation for trigonometric functions • Based on a custom fast calculation engine and used also on macOS in Calcline and TS Calc (available on the Mac App Store). • Uses long double calculation (High precision with up to 9 decimal digit precision) • Works great in Portrait and Landscape mode • Works great on iPad as SlideOver FACILITIES: • A calculation area where you can insert algebraic expressions and immediatly see the result as you type • A Variable table where you can insert infinite variables with custom values, Variables can be created as result of calculations (x=1+1) will create automatically the variable x inside the table assigning the value = 2 • A constant table with constant value usable in calculations. Off course constant can't be assigned by calculation • A log with all the result , available step by step or in concise format AVAILABLE FUNCTIONS sqrt cbrt sin cos tan asin acos atan sinh cosh tanh asinh acosh atanh log log10 exp, exp2 expm1 abs ceil floor pow

Batch rename files, folders and extensions on iPhone, iPad and Mac. Pick a folder in Files, set your rules, check the live preview and rename hundreds of files in one tap. Made a mistake?
