Uniform Distribution

Name

UxHwDoubleUniformDist, UxHwFloatUniformDist — Create a Uniform distribution.

Synopsis

#include <uxhw.h>

double	UxHwDoubleUniformDist(double a, double b);
float	UxHwFloatUniformDist(float a, float b);

Description

The UxHwDoubleUniformDist() function, on architectures that associate distributional information with floating-point values, creates a Uniform distribution with parameters a and b and associates it with its return value. The particle return value is the mean value of a Uniform distribution with parameters a and b.

Parameters

• a $\in (-\infty, b]$ — The lower bound of the Uniform distribution.
• b $\in [a, \infty)$ — The upper bound of the Uniform distribution.

Return values

The UxHwDoubleUniformDist() function returns the mean value of a Uniform distribution with parameters a and b and associates it with a Uniform distribution with parameters a and b. If a = b, the function returns a.

Illegal parameter values

If b < a, the function returns NaN. If a or b is NaN, or b is INFINITY, the function returns -NaN. See Handling of NaN.

Examples

#include <stdio.h>
#include <uxhw.h>

int
main(void)
{
  double	value = UxHwDoubleUniformDist(0.1, 1.0);
  printf("value = %lf\n", value);

  return 0;
}
