Perform complex mathematical calculations with precision
The Scientific Calculator is a comprehensive mathematical tool designed for students, engineers, and scientists. It goes beyond basic arithmetic to provide advanced functions for trigonometry, logarithms, exponents, and more, enabling users to solve complex equations and perform precise calculations for academic and professional work.
Our calculator provides high precision results suitable for academic and professional use. It handles up to 15 significant digits for most operations, though displayed results may be rounded for readability.
The trigonometric functions (sin, cos, tan) currently operate in radians by default. For degree calculations, you'll need to convert your angle (multiply by π/180) before using these functions. We're working on adding a degree/radian toggle in a future update.
To calculate a percentage of a number, multiply the number by the percentage expressed as a decimal. For example, to find 15% of 80, enter 80 × 0.15 = 12. For percentage increases or decreases, use the appropriate formula with addition or subtraction.
The calculator displays your most recent expression in the history line above the main display. Currently, it shows only the last calculation. We're planning to implement a more comprehensive calculation history feature in the future.
The log function calculates the base-10 logarithm (common logarithm), while ln calculates the base-e logarithm (natural logarithm). Log is often used in engineering and chemistry, while ln is common in calculus, statistics, and natural sciences.
