| <p>The distribution function uniform_real models a random distribution. On each invocation, it returns a random floating-point value uniformly distributed in the range [min..max). The value is computed using std::numeric_limits<RealType>::digits random binary digits, i.e. the mantissa of the floating-point value is completely filled with random bits.</p> |
| <p>Note: The current implementation is buggy, because it may not fill all of the mantissa with random bits. </p> |
