MilesianStrings may contain either or both of two components: the first gives positive integers, the second gives fractional units. If the string includes both components, the rightmost significant character of the integer component must be a single quote character, and the rightmost significant character of the fractional component must be a double quote character. If the string consists only of a fractional component, the rightmost significant character must be a double quote character. If the string consists only of an integer component, it may optionally include a single quote as the rightmost significant character.
Within the integer component, white space is not significant: only digit characters and the comma indicating the place column of thousands digits are considered in computing an integer value.
Fractional expresssions represent a sum of unit fractions. White space separates unit fractions that should be added together.
The string ε' 𐅵 δ" has two components. We can verify that it has an integer component, and determine that its integer component is ε', and its fractional component is 𐅵 δ".
The string ε has only one component. We can determine that it has an integer component, and that its integer component is ε.
The string γ" (1/3) has only one component. We can determine that it does not have an integer component.
