The Nextafter32
function is used to find the next representable float32
value after/between the two provided arguments. This function is basically the 32-bit version of the Nextafter
function. Nextafter32
returns the number immediately after x
that is between x
and y
(x
and y
being the first and second arguments for the function).
To use the Nextafter32
function, you must import the math
package in your file and access the Nextafter32
function within it using the .
notation (math.Nextafter32
). Here, Nextafter32
is the actual function, while math
is the Go package that stores the definition of this function.
The definition of the Nextafter32
function inside the math
package is as follows:
The Nextafter32
function takes two arguments of type float32
:
x
: This is an argument of type float32
. The Nextafter32
function finds the next representable float32
value after x
.
y
: This is an argument of type float32
. The Nextafter32
function finds the next representable float32
value after x
that is in the direction of y
.
The Nextafter32
function returns a single value of type float32
that represents the next representable float32
number after x
that is in the direction of y
.
Some special cases are when you pass something that is infinity, 0
, or NAN
as an argument:
If both arguments are the same value, let’s say x
, then the Nextafter32
function returns that value (x
).
If either of the two arguments is of type NAN
, then the return value is also NAN
.
Below is a simple example where we find out the next representable float32
number after $5.35$ towards $1$:
package mainimport("fmt""math")func main() {var x float32 = 5.35y := math.Nextafter32(x,1)fmt.Print("The next representable float32 after ", x," is ", y)}
The example below shows how the Nextafter32
function handles two identical arguments:
package mainimport("fmt""math")func main() {y := math.Nextafter32( 1 ,1)fmt.Print("The next representable float32 after ", 1," is ", y)}
