About NCalc Scientific Calculator +
◉ Main calculator features
• Natural display allows you to enter equations as you write them on paper, using fractions, roots, exponents and more to display the same as it is written in a textbook.
• Keyboard layout is designed exactly as same as calculator 115 es plus, 991 es plus, 300 es plus and 991 ex
• Calculator supports calculating in two modes: symbolic and numeric, so you can perform fraction calculation.
• Arbitrary Precision integers
• Equation solver can solve general equation, cubic, quadratic and quartic equation, the calculator also solves inequality.
• Calculus calculator can calculate derivative, integration and find limit of expression.
• Complex number calculation
• Base N calculation (binary, decimal, hexadecimal and octal)
• Statistical calculation and regression calculation (include regression plotter)
• Table Generator generates table base on expression.
• Matrix and vector calculation
• The calculator includes six output types (fraction, mixed fraction, decimal, repeat decimal, degrees/minutes/second and polar coordinates) and three angle units (degree, radian, grade)
