Function Documentation

to_number()

template<typename T>

T adtf::base::string_conversion::to_number ( std::string_view value, int base = 0 )

inline

Convert a string representation of an integer to a numeric value of type T.

Supports an optional leading sign ('+' or '-') as well as the base prefixes "0x"/"0X" (hexadecimal), "0b"/"0B" (binary) and a leading '0' (octal). A negative value is only accepted when T is a signed type; the most negative value (e.g. "-0x80" for int8_t) is representable.

Template Parameters

T	The numeric type the string gets converted to.

Parameters

[in]	value	String to convert.
[in]	base	Numeric base to use. When 0 (the default), the base is auto-detected from the prefix (see above), otherwise value is parsed using the given base.

Warning

When an explicit base (non-zero) is passed together with a prefixed value (e.g. "0x" or "0b"), the behavior is undefined: the prefix is not stripped and the result depends on the underlying conversion backend.

Returns

Numeric value parsed from value.

Exceptions

std::out_of_range	If the parsed value does not fit into the numeric limits of T.
std::runtime_error	If value is not a valid number, contains trailing characters, or carries a negative sign while T is an unsigned type.
