Syntax of Erfc() Function in Go Language

The syntax of Erfc() function in Go Language is:

func Erfc(x float64) float64

Note: float64 is a data type in Go language which has IEEE-754 64-bit floating-point numbers.
Special cases are:
Erfc(+Inf) = 0
Erfc(-Inf) = 2
Erfc(NaN) = NaN

 

Parameters of Erfc() Function in Go Language

x – Where x is any Valid float64 Input value. This parameter is required.

 

Error Handling

If the x parameter is not a number (numeric value) Erfc() function returns an error .
If there is no argument (x – input value) passes to the function, then the compiler will produce an error.

 

Return Value of Erfc() Function in Go

Erfc() function will return the complementary error function of the given input(x – parameter).
