# fmt_number()


Format a number with a fixed number of decimal places and a thousands separator.


Usage

``` python
fmt_number(
    x,
    *,
    decimals=2,
    sep_mark=",",
)
```


## Parameters


`x: float`  
The number to format.

`decimals: int = ``2`  
The number of decimal places.

`sep_mark: str = ``","`  
The character used to separate groups of thousands.


## Returns


`str`  
The formatted number.


## Examples

By default, numbers get two decimal places and a comma between groups of thousands:


``` python
from tinytab import fmt_number

fmt_number(1234567.891)
```


    '1,234,567.89'


Use `decimals=` to change the precision, and `sep_mark=` for a different separator:


``` python
fmt_number(1234567.891, decimals=0, sep_mark=" ")
```


    '1 234 568'
