ReactOS Calc implements the most commonly used algebraic functions.
It isolates the integer part of the number shown into the output display.
+ 
The integer part of the number is discarded and the fractional part stays on the output display.
Square function. It calculates the square of the number shown on the output display.
+ , 
It returns the positive square root of the number shown on the output display.
If the current number is negative, then the error message will be displayed.
When working with standard layout, the [Sqrt] button is a shortcut to this function.
Cube function. It calculates the cube of the number shown on the output display.
+
It returns the cube root of the number shown on the output display.
Power function. It calculates the power of X elevated to Y.
+
Root function. It calculates the Y-th root of X.
Reciprocal. It divides 1 by the number shown on the output display.
Factorial. It calculates the factorial of the integer part of the number shown into the output display.
The calculation is defined within these limits:
0 <= n <= 170
Natural logarithm. It calculates the natural logarithm of the current number.
ReactOS Calc assumes the Nepero's constant to be:
e=2.7182818284590452354
The calculation is defined for x > 0.
+
Natural anti-logarithm. It calculates the power of the Nepero's constant to the current number.
Decimal logarithm. It calculates the logarithm of the current number to base 10.
The calculation is defined for x > 0.
+
Decimal anti-logarithm. It calculates the power of 10 to the current number.
