## Overview
In order to find the predecessor of a floating-point number, we use the **`prev_float` method**.

## Syntax
```ruby
float_value.prev_float
```
## Parameters
**`float_value`**: This is the float value whose predecessor value we want to find. 
## Return value
The predecessor of `float_value` is returned.
## Code example


# create some float values
f1 = 2.3
f2 = -1.0
f3 = 0.1111111 
f4 = 200.00

# get previous values
# and print results
puts f1.prev_float
puts f2.prev_float
puts f3.prev_float
puts f4.prev_float

## Explanation
* **Lines 2-5:** We create some float values: `f1`, `f2`, `f3`, and `f4`.
* **Lines 9-12:** We invoke the `prev_float` method on the float values and print the results to the console.

What is the float.prev_float method in Ruby?

Find a float's predecessor in Ruby using the prev_float method: `float_value.prev_float`.
