C++ Math nextafter()
The nextafter() function represents the next representable value in a specific direction.
Suppose two numbers are 'from' and 'to'. Therefore, the nextafter() function finds the next value of 'from' in the direction of 'to'.
Note: If any argument is long double, then the return type is long double. If not, the return type is double.
( from, to): These are the floating point values.
Let's see a simple example when the value of 'from' and 'to' are equal.
Values of from and to are:6.7, 6.7 6.7
In the above example, values of 'from' and 'to' are equal. Therefore, the function returns the value of 'from'.
Let's see a simple example when 'from' and 'to' are of same type.
Values of from and to are:0, 6 4.94066e-324
In the above example, 'from' and 'to' are of same type but are unequal. The nextafter() function returns the value i.e 4.94066e-324
