Calculates the complementary error function value of a floating-point number.

[Format]

#include <math.h>

double erfc(double d);

float erfcf(float d);

long double erfcl(long double d);

[Parameters]

d Value for which the complementary error function value is to be computed

[Return values]

Complementary error function value of d

[Remarks]

A range error occurs if the absolute value of d is too large.
