Calculator X — Dev & Graphs

all-in-one calculator for coders & students: convert DEC/BIN/HEX/OCT, run bitwise ops, plot 2D & 3D functions, and crunch matrices.

Calculator X is a powerful calculator built for developers, students, and anyone who works with numbers beyond the basics.

PROGRAMMER'S CALCULATOR Work seamlessly across decimal, binary, hexadecimal, and octal. Toggle individual bits directly on a 64-bit grid, perform bitwise operations (AND, OR, XOR, NOT), and watch all four bases update in real time as you type.

2D FUNCTION GRAPHING Plot any mathematical function of x instantly. Pan and pinch-to-zoom to explore the curve at any scale. Perfect for visualizing equations, finding intersections, and understanding function behavior.

3D SURFACE PLOTTING Enter any function of x and y and see it rendered as a live 3D surface. Rotate with one finger, zoom with a pinch, and pan with two fingers. Gradient coloring makes it easy to read the shape of any surface.

MATRIX CALCULATOR Work with matrices up to 8×8. Perform addition, subtraction, multiplication, transpose, determinant, and inverse — all in one place. Results scroll so nothing gets cut off no matter how large your matrix is.
