thoschCalc - calculator

thoschCalc is a quick and easy to use calculator that immediately calculates the result as you enter the term. In addition to the basic arithmetic operations, the constants can be used
- pi, g, e, c(0), G, m(u), e(u)
and functions
- sqr(x), sqrt(x), pow(b;e)
- sin(x), cos(X), tan(x), acos(x), asin(x), atan₂(a;b)
- exp(x), ln(x), log(x), log₁₀(x), log₂(x)
- abs(x), trunc(x), round(x), mod(a;b)
- max(x1;...;xn), min(x1;..;xn)
be integrated into the calculation steps.
Numbers of different units of the same dimension are automatically converted into the set unit of the calculation result before the calculation:
- Length: mm, cm, dm, m, km, inch, foot, yard, mi, nm
- Area: mm², cm², dm², m², km², inch², foot², yard², mi², nm², ha
- Volume: mm³, cm³, dm³, m³, km³, inch³, foot³, yard³, mi³, nm³, ml, l, oz, oz(us), gal, gal(us), bbl, bbl(us)
- Weight: µg, mg, g, kg, t, lbs
- Time and date: t, ms, s, min, h, day, week, year (28), year (29 = leap year), date, time
- Temperature: Celsius, Fahrenheit, Kelvin
- Speed: m/s, km/h, mph, fps, kn
- Flow: cm³/s, cm³/min, cm³/h, cm³/day, cm³/year, l/s, l/min, l/h, l/day, l/year, m³/s, m³/min , m³/h, m³/day, m³/year, km³/s, km³/min, km³/h, km³/day, km³/year
The entered term and the result can be transferred to other programs by long pressing and copying or pasting (copy & paste). The color of the background can be changed by shaking (iOS only) or via a dialog.
The free version can be used 10 times with the full range of functions. From version 6.0 onwards, an annual subscription must be taken out (the further development does not only live on air and love and not every expansion is permanently free despite a previous one-off purchase) or only calculations without constants, functions or units are possible.
In the free version, the last 5 previous calculations can be restored via a selection box or by swiping vertically on the input field. An in-app purchase can increase the number of previous calculations to 500. With a further in-app purchase, the history (optionally including the results) can be displayed in a separate table in which you can search for previous terms in order to use them for further calculations.
