In Elixir, you can use the `:erlang.float_to_binary/2`

function to set the decimal precision everywhere in your code. This function takes two arguments - the number you want to format and the options you want to set for the formatting. One of the options you can use is the `:decimals`

option to specify the number of decimal places you want to display. By using this function across your codebase, you can ensure that all floating-point numbers are formatted with the desired precision.

## How to adjust decimal format in Elixir?

In Elixir, you can use the `Decimal`

module from the `decimal`

library to adjust the decimal format. Here is an example of how to adjust the number of decimal places:

1 2 3 4 5 6 7 8 |
# Import the Decimal module import Decimal # Adjust the decimal format to have 2 decimal places decimal = Decimal.new("123.456") adjusted_decimal = Decimal.round(decimal, 2) IO.puts(adjusted_decimal) # Output: #Decimal<"123.46"> |

In this example, the `Decimal.round/2`

function is used to adjust the decimal format to have 2 decimal places. You can adjust the format according to your specific requirements by changing the parameters of the `Decimal.round/2`

function.

## What is the function for setting global decimal precision in Elixir?

In Elixir, the function for setting global decimal precision is `Decimal.set_precision/1`

. This function takes an integer as input, which represents the number of decimal places to use for all decimal calculations in the current process.

For example, to set the global decimal precision to 10 decimal places, you would call `Decimal.set_precision(10)`

. This will ensure that all decimal calculations performed in that Elixir process will be rounded to 10 decimal places.

## How to set the decimal precision globally in Elixir?

In Elixir, you can set the decimal precision globally by using the `Decimal`

library. To set the precision globally, you can use the `Decimal.set_global_precision/1`

function.

Here is an example of how to set the decimal precision globally to 4 in Elixir:

```
1
``` |
```
Decimal.set_global_precision(4)
``` |

By setting the global precision, all decimal operations in your Elixir application will use the specified precision. This means that any calculations or conversions involving decimals will be rounded to the specified number of decimal places.

## What is the strategy for specifying decimal precision in Elixir?

In Elixir, the Decimal module can be used to specify decimal precision. The Decimal module provides functions to perform arithmetic operations on decimal numbers with a specified precision.

To specify decimal precision, you can use the `new/2`

function to create a new decimal number with a specific number of decimal places. For example, to create a decimal number with 2 decimal places, you can use:

```
1
``` |
```
Decimal.new("10.12345", 2)
``` |

This will create a decimal number with a precision of 2 decimal places, which will be rounded to `10.12`

. You can then perform arithmetic operations on this decimal number with the specified precision.

You can also use the `round/2`

function to round a decimal number to a specific number of decimal places. For example, to round a decimal number to 3 decimal places, you can use:

```
1
``` |
```
Decimal.round(decimal_number, 3)
``` |

This will round the decimal number to 3 decimal places.
