## Detailed Description

### template\<typename \_RealType = double\>class std::uniform\_real\< \_RealType \>

Uniform continuous distribution for random numbers.

A continuous random distribution on the range \[min, max) with equal probability throughout the range. The URNG should be real-valued and deliver number in the range \[0, 1).

### template\<typename \_RealType = double\> std::uniform\_real\< \_RealType \>::uniform\_real (\_RealType\_\_min = `_RealType(0)`, \_RealType\_\_max = `_RealType(1)`)` [inline]`, ` [explicit]`

Constructs a **uniform\_real** object.

**Parameters:**

*\_\_min* \[IN\] The lower bound of the distribution. \
 *\_\_max* \[IN\] The upper bound of the distribution.

**Parameters:**

*\_\_os* An output stream. \
 *\_\_x* A uniform\_real random number distribution.

**Returns:**

The output stream with the state of `__x` inserted or in an error state.
