In addition to the support manager functions you can use for mathematical operations, LabVIEW supports a number of other mathematical functions. The following functions are implemented as defined in The C Programming Language by Brian W. Kernighan and Dennis M. Ritchie.
double atan(double);
double cos(double);
double exp(double);
double fabs(double);
double log(double);
double sin(double);
double sqrt(double);
double tan(double);
double acos(double);
double asin(double);
double atan2(double, double);
double ceil(double);
double cosh(double);
double floor(double);
double fmod(double, double);
double frexp(double, int *);
double ldexp(double, int);
double log10(double);
double modf(double, double *);
double pow(double, double);
double sinh(double);
double tanh(double);
