# _CP_precision

_CP_precision is equivalent to the `precision *number*` BASIC statement.

## Syntax

```
void _CP_precision(int number)
```

## Description

This function affects the precision
of the _CP_rs_ and the _CP_sr_ functions.

## Example(s)

This example displays `"1.12"` since the conversion is truncated to the precision
of 2.

```
CPSTR * s = _CP_mkstr("1.12345");
double r;
_CP_precision(2);
r = _CP_sr_(s);
_CP_unix_env();
printf("%g\n", r);
_CP_str_free(s);
```
