Example:
The following 25 losses, due to wind-related property damages, were recorded to the nearest thousand dollars.
For convenience, they have been ordered (by row).

Leaf unit is in thousands of dollars
Stem units are in thousands of dollars and tens of thousands of dollars. 15|2

15 2 represents 15+2 = 17 thousand dollars.

 

Example:
For each of 18 preserved cores from oil-wet carbonate reservoirs, the amount of residual gas saturation after a solvent injection was measured at water-flood out. Observations, in percentage of pore volume, were:
 23.5      31.5        34.0         46.7       45.6       32.5       41.4       37.2        42.5

Leaf unit is in ones and one tenth percentage
Stem units are in tens of percentage. Note that

2 3.5 represents 23.5 percent.
