/// # Lexical representation
|
|
/// Decimal has a lexical representation consisting of a finite-length sequence of
|
|
/// decimal digits separated by a period as a decimal indicator.
|
|
/// An optional leading sign is allowed. If the sign is omitted, `"+"` is assumed.
|
|
/// Leading and trailing zeroes are optional. If the fractional part is zero,
|
|
/// the period and following zero(es) can be omitted.
|
|
/// For example: `-1.23`, `12678967.543233`, `+100000.00`, `210`.

///
|
|
/// # Canonical representation
|
|
/// The canonical representation for decimal is defined by prohibiting certain
|
|
/// options from the Lexical representation. Specifically, the preceding optional
|
|
/// `"+"` sign is prohibited. The decimal point is required. Leading and trailing
|
|
/// zeroes are prohibited subject to the following: there must be at least one
|
|
/// digit to the right and to the left of the decimal point which may be a zero.
