Section 8. Working with Data Files on the PC
SpaMax(x..y) returns the maximum value of elements x
through y.
Examples:
SpaMax(1..7) = 1200
SpaMax(1,2,5) = 176
SpaMin(x..y) returns the minimum value of elements x through y.
Examples:
SpaMin(1..7) = –7.89
SpaMin(1,2,5) = 55.1
SpaSd(x..y) returns the standard deviation of elements x through y.
Examples:
SpaSd(1..7) = 394.57
SpaSd(5,2,1) = 49.607
Sqrt(x) returns the square root of element x.
Examples:
Sqrt(3) = 34.641
Sqrt(3^ 2.0) = 1200
8.2.3.1.11 Time Series Functions, Details, and Examples
TABLE 8-7. Time Series Functions
TIME SERIES FUNCTIONS
Avg(x;n) = Average
Blanks(x;n) = Number of blanks in element
Count(x;n) = Number of data points in element
Max(x;n) = Maximum
Min(x;n) = Minimum
RunTotal(x;n) = Running total
Sd(x;n) = Standard deviation
Smpl(x;n) = Sample raw value
SmplMax(x;y;n) = Sample (y) on a maximum (x)
SmplMin(x;y;n) = Sample (y) on a minimum (x)
Total(x;n) = Totalize
WAvg(x;n) = Unit vector mean wind direction (in degrees)
NOTE: x can be an element or a valid expression. n is optional
and is the number of arrays to include in the function. Date and
Edate can be used for the “n” in the Time Series functions to
produce monthly output (see TABLE 8-8, Special Functions).
