General Calculator
This version sums a comma- or space-separated list of finite numbers. Its mathematical operation is addition, not free-form expression evaluation; use Scientific Calculator for expressions.
Tape Calculator
Parse the entered list into numeric items, add all items, and display the sum and item count. It does not retain a persistent printed calculator tape.
Fraction Calculator
Divide the entered numerator by the denominator and display its decimal form to four decimal places. The denominator cannot be zero; this is not fraction simplification.
Scientific Calculator
Evaluate a supported mathematical expression with operator precedence, parentheses, constants and supported functions using a restricted parser, not JavaScript execution.
Triangle Calculator
Triangle area = base × perpendicular height / 2. Both dimensions must be nonnegative and use the same length unit; the result uses that unit squared.
GPA Calculator
GPA = sum(grade points × course credits) / sum(course credits). Match each grade to one positive credit value; grades must be on the displayed 0–4 scale.
