Example: lr_convert_double_to_double | Parameter Functions

## Arguments

Name | Comments
--- | ---
source_param_name | The name of the parameter containing the double to be reformatted.
format_string | A printf-style format specifier.
target_param_name | The parameter to contain the reformatted string.

lr_convert_double_to_double formats the string representation of a double value using a printf-style format specifier. The target parameter is created if it does not exist.

The maximum length of the output string to be written to target_param_name is 63 characters. Create your format string accordingly.

If the input string is not a pure number string, as many characters as possible are converted. The rest are ignored. A string that does not begin with a character that can be converted causes an error.

For example:

- “1234ABCDF” is converted to 1234.
- “312.123.32.23123” is converted to 312.123 .
- “MyProduct” and “ABC123PC” cause errors.
