Function Documentation
◆ atof_dpi()
| double atof_dpi | ( | char * | str | ) |
Replacement of atof(), which works whether string contains decimal dots or decimal commas. Possible commas are replaced by dots in the argument string.
Referenced by atof_with_check().
◆ atof_with_check()
| int atof_with_check | ( | char * | double_as_string, |
| double * | result_value | ||
| ) |
Converts a string to float using strtod(), but if its return value is zero this function checks that argument string actually contains a number.
- Returns
- Returns 0 if successful, and 1 in case of an error.
- Parameters
-
double_as_string String which is converted to a double result_value Pointer to the double float

Here is the call graph for this function:
◆ dec_comma_is()
| int dec_comma_is | ( | char * | str | ) |
Checks whether argument string contains a decimal comma instead of dot.
- Returns
- Returns 1 if decimal comma is found and 0 if not found.
◆ dec_nr()
| int dec_nr | ( | char * | str | ) |
Returns the number of decimapl places in the argument string, representing a floating point value. String can contain either decimal dots or commas.
