lr_convert_double_to_integer

Converts the string representation of a double value to the string representation of an integer.

int lr_convert_double_to_integer( char *source_param_name, char * target_param_name );

Arguments

lr_convert_double_to_integer converts the string representation of a double value to an integer string by discarding the fractional part of the double. The target parameter is created if it does not exist.

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.

Return Values

This function returns LR_PASS (0) on success, and LR_FAIL (1) on failure.

Parameterization

Standard parameterization is not available for this function.

Example

In the following example, lr_convert_double_to_integer converts the string representation of a double to the string representation of an int.

lr_save_string("1.0502731456E7","sourceParam");
lr_save_string("10062731.0","sourceParam2");

lr_convert_double_to_integer("sourceParam","outparam");
lr_output_message("[%s] converted to: [%s]",
lr_eval_string("{sourceParam}"),lr_eval_string("{outparam}"));

lr_convert_double_to_integer("sourceParam2","outparam");
lr_output_message("[%s] converted to: [%s]",
lr_eval_string("{sourceParam2}"),lr_eval_string("{outparam}"));
 

Example: Output:
Action.c(16): [1.0502731456E7] converted to: [10502731]
Action.c(19): [10062731.0] converted to: [10062731]
