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
