asciiStringToUnsigned
bool asciiStringToUnsigned(string str, uint base, ulong min, ulong max, out ulong outNum)A convenience function for converting a string to an unsigned number.
This function assumes that str contains only a number of the given base that is within inclusive bounds limited by min and max. If this is true, then the converted number is stored in out_num. An empty string is not a valid input. A string with leading or trailing whitespace is also an invalid input. A string with a leading sign (`-` or `+`) is not a valid input for the unsigned parser.
base can be between 2 and 36 inclusive. Hexadecimal numbers must not be prefixed with "0x" or "0X". Such a problem does not exist for octal numbers, since they were usually prefixed with a zero which does not change the value of the parsed number.
Parsing failures result in an error with the G_NUMBER_PARSER_ERROR domain. If the input is invalid, the error code will be errorGLib.NumberParserError.INVALID. If the parsed number is out of bounds - errorGLib.NumberParserError.OUT_OF_BOUNDS.
See funcGLib.ascii_strtoull if you have more complex needs such as parsing a string which starts with a number, but then has other characters.
Parameters
str | a string |
base | base of a parsed number |
min | a lower bound (inclusive) |
max | an upper bound (inclusive) |
outNum | a return location for a number |
