Express localeToFixed(D, 1) as a fraction.
D
The number T is in the tenths place,
so we have cardinalThrough20(T) plural_form(decimalPlaceNames[1], T).
CardinalThrough20(T) plural_form(decimalPlaceNames[1], T)
can be written as fraction(T, 10).
Express localeToFixed(D, 2 ) as a fraction.
D
The number H is in the hundredths place,
so we have cardinalThrough20(H) plural_form(decimalPlaceNames[2], H).
CardinalThrough20(H) plural_form(decimalPlaceNames[2], H)
can be written as fraction(H, 100).
Add the two parts together.
fraction( T, 10 ) + fraction( H, 100 )
= fraction( T * 10, 100 ) + fraction( H, 100 )
= fraction( T * 10 + H, 100 )
