Model loan amortization CSV schedules, compound growth, ROI/CAGR, and break-even thresholds alongside scientific expression evaluation, survey/Imperial/US metrology (length, area, volume), BigInt base labs, and Ohm's Law / RF dBm calculators.
Loan, Investment & ROI Finance Studio
Model loan/mortgage amortization with extra principal payments & CSV export, project compound interest growth, compute margin vs markup/tax, and evaluate break-even, ROI, and CAGR.
Engineering Unit, Length, Area, Volume & Base Studio
Convert 12 precision measurement categories including Length/Distance (metric, surveying, nautical, astronomical), Area (m², are, ha, acre), Volume (US Liquid vs UK Imperial), Angle, SI/IEC storage, BigInt Base 2–36 & Ohm/dBm.
Scientific Calculator & Formula Notebook Studio
Evaluate scientific expressions safely via mathjs AST parsing across Degrees, Radians, and Gradians (gon) with inverse/hyperbolic trig, logarithms, factorials, nCr/nPr, memory registers, history tape, and multi-line variable sheets.
Common workflows in Finance & Engineering Studios
Loans, compound growth, ROI & break-even
Export full monthly mortgage amortization CSVs, model extra principal payments, calculate annualized CAGR, and find unit break-even points.
Scientific math, US vs Imperial metrology & electrical labs
Evaluate recursive-descent math expressions without eval(), convert light-years to Ångströms, hectares/ares/acres, and US vs Imperial gallons, inspect 64–256-bit integers, and compute Ohm's Law and dBm ↔ mW.
