Enumeration Details:

NFHint

enum class alib::expressions::detail::ASTLiteral::NFHint

strong

This is a list of flags that store information obbout the format of the literal given in the expression string. This information is used with the generation of a normalized version of the literal.

Enumerator
NONE	No hint.
Scientific	Float was given in scientific format.
Hexadecimal	Integral value was given in hexadecimal format.
Octal	Integral value was given in octal format.
Binary	Integral value was given in binary format.
