# PHP | stats_rand_gen_funiform() Function

Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP stats_rand_gen_funiform() Function.

The built-in PHP stats_rand_gen_funiform() function generates uniform float between low (exclusive) and high (exclusive).

## Syntax

Following below is the syntax to use this function -

`float stats_rand_gen_funiform( float \$low, float \$high )`

## Parameter Details

Sr.NoParameterDescription
1

low

The lower bound (inclusive)

2

high

The upper bound (exclusive)

## Return Value

This built-in PHP function returns a random deviate from uniform distribution from low to high.

## Dependencies

This built-in function was first introduced in statistics extension (PHP version 4.0.0 and PEAR v1.4.0). In this tutorial guide, we used the latest release of stats-2.0.3 (PHP v7.0.0 or newer and PEAR version 1.4.0 or newer).

### Example1

Following example computes the random deviation from the uniform distribution by passing \$low < \$high-

```<?php
\$x = stats_rand_gen_funiform(1.5, 2.5);
var_dump(is_float(\$x));
var_dump(\$x > 1.5);
var_dump(\$x < 2.5);
?>```

#### Output

When the above code is executed, it will produce the following result -

```bool(true)
bool(true)
bool(true)
bool(true)```

### Example2

Following example computes the random deviation from the uniform distribution -

```<?php
\$x = stats_rand_gen_funiform(1.5, 1.5);
var_dump(\$x);
?>```

#### Output

When the above code is executed, it will produce the following result -

`float(1.5)`

### Example3

The following below is an error case. In the below example, we have passed low > high. A warning is shown in logs -

```<?php
// error cases
var_dump(stats_rand_gen_funiform(2.5, 1.5));    // low > high
?>```

#### Output

The above code will produce the following result and a warning in logs PHP Warning: stats_rand_gen_funiform(): low greater than high. low: 2.500000E+0 high: 1.500000E+0

`bool(false)`

Alright guys! This is where we are going to be rounding up for this tutorial post. In our next tutorial, we are going to be discussing about the built-in stats_rand_gen_gamma() Function.
