FunctionHyperbolic cotangent function
Syntax C/C++#include <VFmath.h>
int VF_coth( fVector Y, fVector X, ui size );
int VFx_coth( fVector Y, fVector X, ui size, float A, float B, float C );
C++ VecObj#include <OptiVec.h>
int vector<T>::coth( const vector<T>& X );
int vector<T>::x_coth( const vector<T>& X, const T& A, const T& B, const T& C );
Pascal/Delphiuses VFmath;
function VF_coth( Y, X:fVector; size:UIntSize ): IntBool;
function VFx_coth( Y, X:fVector; size:UIntSize; A, B, C:Single ): IntBool;
Descriptionnormal versions: Yi = coth ( Xi )
expanded versions: Yi = C * coth ( A*Xi+B )
Error handlingSING errors lead to a default result of 0.0 (the mean of +HUGE_VAL and -HUGE_VAL); OVERFLOW errors lead to a default result of ±HUGE_VAL.
Return valueFALSE (0), if no error occurred, otherwise TRUE (non-zero).
