The library is able to interpret several functions. Their length cannot be longer than 4 characters. Indeed wxEcEngine::Function2ID() converts the name (8 or 16 bits per char) into an integer (32 bits). We assumed it should be faster to interpret.

Normal functions

abs : the absolute value, it removes the sign
ceil : the smallest integer greater than or equal to x
cub : x^3, safe way to compute such an exponent
deg : converts from radian to degree
even : =1 if even, else =0
exp : the exponential value
hvi : Heaviside's function, =0 if x<0, =1 if x>=0
int : the largest integer less than or equal to x
inv : inverts, 1/x
floor : not supported, see int
ln : the neperian logarithm
lnep : see ln
log : the logarithm base 10
not : =1 if =0, else =0
odd : =1 if odd, else =0
rad : converts from degree to radian
rand : generates a random number, modulo the given value if not null
sgn : the sign, -1 or +1. Zero returns +1.
sqr : x^2, safe way to compute such an exponent
sqrt : the root square

Trigonometric functions

acos : the secant (inverse of cosine)
acsh : the inverse of the hyperbolic cosine
asin : the cosecant (inverse of sine)
asnh : the inverse of the hyperbolic sine
atan : the cotangent (inverse of tangent)
atnh : the inverse of the hyperbolic tangent
cos : the cosine
cosh : the hyperbolic cosine
sin : the sine
sinc : the cardinal sine (radian)
sinh : the hyperbolic sine
tan : the tangent
tanh : the hyperbolic tangent

Overriden functions in the complex domain

These functions are not supported by wxEcEngine. Their use is dedicated to C++ developers who use our wxEcComplex class to handle complex numbers.

The definition of these functions is explicitely written in ec_complex.h. So you must include this file before being able to use them.

#include "ec_complex.h"

List :

sqrt : the root square
exp : the exponential value
log : the natural logarithm (don't confuse with LN which is not overriden)
cos : cosine
sin : sine
tan : tangent
csc : cosecant
sec : secant
cot : cotangent
cosh : hyperbolic cosine
sinh : hyperbolic sine
tanh : hyperbolic tangent
csch : hyperbolic cosecant
sech : hyperbolic secant
coth : hyperbolic cotangent
