Calculatrice
The French online calculator built for real expressions — type a full formula with parentheses, trig functions and powers, watch the live preview, then press equals.
What this calculator handles
The keypad accepts complete expressions — nest parentheses, mix trig with powers, chain logarithms. sin(30)+log(100)^2 evaluates as one expression.
Precedence follows the standard convention: functions first, then powers, then multiplication and division. 2^3^2 is 2⁹ = 512, not 64.
Degrees or radians
In DEG mode sin(30) is 0.5. If a result looks wrong by a factor of about 57, the mode is the usual culprit: 1 radian is 57.3°.
Frequently asked questions
Does it follow order of operations?
Yes — functions, then powers, then multiplication and division, then addition and subtraction. Parentheses override.
How do I enter a negative number?
A leading minus is read as negation, so −5² is −(5²) = −25.
Why does sin(30) differ between DEG and RAD?
The mode changes the unit: 30 radians is about 1,719 degrees.
Is the history saved?
Only for the current session — the calculator stays cookie-free.
