Edate(doy;y) = Convert Julian day to
European date, where
doy=day of year and
y=year. Format is DD-
MM. When used as the
interval, n, with Time
Series Functions (see
example, this Section),
Edate triggers monthly
time series summaries.
"Label" = Insert Comment in Output
file. (Label is anything
within the quote marks.)
Line = Number of lines written to
Output file.
.PA = Page break to printer or to
the .RPT file.
4.3.6.1 MATHEMATICAL FUNCTIONS,
DETAILS AND EXAMPLES
The following array of PRINTABLE ASCII data
will be used for all Mathematical function
examples.
0105 0176 1200 -07.89 55.10 12.45 270.5
Abs(x) returns the absolute, or
positive value of element x.
Examples:
Abs(4) = 7.89
Abs(4*5) = 434.74
Arctan(x) returns the arc tangent of
element x in degrees.
Examples:
Arctan(7) = 89.788
Arctan(7/6) = 87.365
Cos(x) returns the cosine of
element x in degrees.
Examples:
Cos(5) = .57215
Cos(5-6) = .73551
Exp(x) returns the exponential
base e to the power of
element x.
Example:
Exp(4) = .00037
Frac(x) returns the fractional value
of the element x.
Examples:
Frac(4) = -.89
Frac(6+7) = .95
Int(x) returns the integer portion
of the element x.
Examples:
Int(7) = 270
Int(5*6) = 685
Ln(x) returns the natural log of
element x. Examples:
Ln(6) = 2.5217
Ln(7/6*5/1) = 2.4337
Sin(x) returns the sine of element
x in degrees. Examples:
Sin(7) = -.99996
Sin(7-2+5) = .50603
Spatial functions, included under Mathematical
functions, operate on a per Output Array basis.
The average, maximum, minimum, and
standard deviation of a specified group of
elements within an array are calculated.
SpaAvg(x..y) returns the spatial average
of elements x through y.
Examples:
SpaAvg(1..7) = 258.74
SpaAvg(1,4,7) = 122.54
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
4.3.6.2 TIME SERIES FUNCTIONS, DETAILS
