This advanced calculator goes beyond basic arithmetic with scientific and programmer modes — trigonometry, logarithms, powers and roots, and number-base conversion between decimal, hexadecimal, binary, and octal. It is a single tool for the maths a student, engineer, or developer reaches for daily.
Scientific mode
Scientific mode adds the functions a basic calculator lacks: trigonometric functions and their inverses, natural and base-10 logarithms, exponentials, powers, roots, and constants like π and e. It respects the correct order of operations (parentheses, exponents, multiplication and division, then addition and subtraction) so a long expression evaluates the way the maths intends rather than strictly left to right.
Getting the order of operations and angle mode (degrees versus radians) right is where hand calculation most often goes wrong. Entering the whole expression and letting the calculator parse it removes those slips, which matters when one mistake cascades through a longer calculation.
Programmer mode
Programmer mode works in different number bases and bitwise operations, converting a value between decimal, hexadecimal, binary, and octal and showing them side by side. This is everyday work in software and electronics — reading a colour or register value in hex, checking a bitmask in binary, or converting an address. Seeing the same number in every base at once makes the relationships obvious.
Converting the decimal number 255 to hexadecimal and binary.
- 255 in hexadecimal: FF (15×16 + 15).
- 255 in binary: 11111111 (eight ones).
- So 255 = 0xFF = 0b11111111.
Decimal 255 is FF in hex and 11111111 in binary — a single byte fully set.
