PCTL<n>(percentage, value1<, value2,
...>)


n

is a digit from 1 to 5 which specifies the
definition of the percentile to be computed.

percentage

is a numeric constant, variable, or expression
that specifies the percentile to be computed.
Requirement: 
is numeric where,
0
percentage
100. 

value

is a numeric variable, constant, or expression.
The PCTL function returns the percentile
of the nonmissing values corresponding to the percentage. If percentage is missing, less than zero, or greater than 100,
the PCTL function generates an error message.
Note: The formula that is used
in the PCTL function is the same formula that used in PROC UNIVARIATE. For
more information, see SAS Elementary Statistics Procedures in
Base SAS Procedures Guide.
