C++ Math nexttoward()

The nexttoword() function represents the next representable value in a specific direction. The nextafter() and nexttoward() both the functions work similar and return the same value. The only difference occurs in their syntax.

Syntax

Parameter

( from , to ) : These are the floating point values.

Return value

• If 'from' equals to 'to', then it returns the value of 'from'.
• If no error occurs, then the next representable value of 'from' is returned.

Example

Let's see a simple example.

Output:

Values of from and to are:0, -1
-3.6452e-4951

In the above example, the 'from' and 'to' are of different type. The nexttoward() function returns the value i.e -3.6452e-4951.
