Predefined Function Names and Constants

All the predefined functions and constants that KmPlot knows can be shown by selecting Help->Names. They are:

sqr, sqrt

Return the square and square root of a number, respectively.

exp, ln

Return the exponential and natural logarithm of a number, respectively.

log

Returns the logarithm to base 10 of a number.

sin, arcsin

Return the sine and inverse sine of a number, respectively. Note that the argument to sin and the return value of arcsin are in radians.

cos, arccos

Return the cosine and inverse cosine of a number, respectively. Also in radians.

tan, arctan

Return the tangent and inverse tangent of a number, respectively. Also in radians.

sinh, arcsinh

Return the hyperbolic sine and inverse hyperbolic sine of a number, respectively.

cosh, arccosh

Return the hyperbolic cosine and inverse hyperbolic cosine of a number, respectively.

tanh, arctanh

Return the hyperbolic tangent and inverse hyperbolic tangent of a number, respectively.

sin, arcsin

Return the sine and inverse sine of a number, respectively. Note that the argument to sin and the return value of arcsin are in radians.

cos, arccos

Return the cosine and inverse cosine of a number, respectively. Also in radians.

pi, e

Constants representing π (3.14159...) and e (2.71828...), respectively.

These functions and constants and even all user defined functions can be used to determine the axes settings as well. See the section called “The Axes Configuration”.
