Mathematical Functions

Through the mth button you can reach all the built-in mathematical functions and constant values.

The following mathematical functions are available:

e^x Rises the natural number e to the power of the value in the display.
10^x Rises 10 to the power of the value in the display.
y^x Rises the value in the display ten to the power of the next input value.
ln Computes the natural logarithm of the value in the display.
log Computes the 10-based logarithm of the value in the display.
xRooty Computes the root of the value in the display using the next input value as index.
int Extracts the integer part from the value in the display.
frc Extracts the fractional part from the value in the display.
n! Computes the factorial of n.
abs Computes the absolute value of the value in the display.
The following trigonometric functions are available:
sin Computes the sinus of the value in the display, interpreted according to the current angle format.
cos Computes the cosinus of the value in the display, interpreted according to the current angle format.
tan Computes the tangens of the value in the display, interpreted according to the current angle format.
By means of the buttons inv and hyp trigonometric functions can be changed to their inverted or/and hyperbolic form.
The following constants values are available:
PI Generates the pi value (3.14…).
e Generates the natural number (2.72…).
r Generates the angular value of a radian expressed in the currently selected units (1.0 in radians, 57.3… in degrees and 63.66... in grades).
Other available functions are:
ran Generates a random value between 0.0 and 1.0.
equ Equalizes the internal value to what is visible in the display (the value is rounded or truncated according to the currently displayed number of decimals).
