nexttoward()

Returns the next representable value.

  #include <math.h>
  
  double nexttoward(double x, long double y);
  
  float nexttowardf(float x, long double y);
  
  long double nexttowardl(long double x, long double y);    

x

Current representable value.

y

Direction to compute the next representable value.

These functions perform identically to their nextafter counterparts but has these differences:

• The y argument is always of type long double.
• If x equals y, these functions return y converted to x's type

This facility may not be available on configurations of the EWL that run on platforms that do not have floating-point math capabilities.
