About This Tool
This full-featured scientific calculator supports trigonometric functions (with degree/radian toggle), logarithms, exponents, roots, factorials, absolute value, floor/ceiling, and more. It includes memory functions (MC, MR, MS, M+) and a toggleable scientific panel that hides advanced functions for a cleaner basic-calculator experience. The built-in calculation history lets you review and reuse previous results. Optimized for mobile PWA with large touch targets and minimal padding.
