\qquad \begin{align*}
NUM[3] &= NUM[1] \text{ plural_form(decimalPlaceNames[NUM[2]], NUM[1])} \\

Get each number in plural_form(decimalPlaceNames[MAX_P], 2).
\qquad \begin{align*}
NUM[3] &= round(NUM[0] * P)\text{ plural_form(decimalPlaceNames[MAX_P], 2)} \\

Order the numbers: NUMS_SORT_TEX.
Convert back to decimals.
