"the-mass-of" is expressed by the article {lei}. If you have five loaves of 
bread, {le nanba} considers them as five things, while {lei nanba} considers 
them as one.

{pi} is the decimal point. When used with numbers like {ro}, it produces a 
number in the interval [0..1], whereas without {pi} they would be in the 
interval [0..however many things there are]. So, assuming the five loaves of 
bread:
{vo le nanba} means four loaves of bread.
{pivo le nanba} means 4/10 of a single loaf of bread.
{vo lei nanba} means twenty loaves of bread, which is nonsense.
{pivo lei nanba} means two loaves of bread, or 4/10 of each loaf, or any 
combination thereof.
{ro le nanba} means five loaves of bread.
{piro le nanba} means an entire loaf of bread (I'm not sure).
{ro lei nanba} means five loaves of bread, as one mass.
{piro lei nanba} also means five loaves of bread as one mass.
