stats_dens_uniform — Probability density function of the uniform distribution

### 说明

stats_dens_uniform ( float `$x` , float `$a` , float `$b` ) : float

Returns the probability density at `x`, where the random variable follows the uniform distribution of which the lower bound is `a` and the upper bound is `b`.

### 参数

`x`

  The value at which the probability density is calculated

`a`

  The lower bound of the distribution

`b`

  The upper bound of the distribution

### 返回值

The probability density at `x` or `FALSE` for failure.
