atan

atan

Inverse tangent

Result = atan(expression)
expression

spatial, non spatial scalar

Result

dimension of expression directional

Options

if expression is a number: --degrees or --radians

--degrees

direction is given in degrees (default)

--radians

direction is given in radians

Operation

For each cell, calculates the inverse tangent of the cell value on expression and assigns it to Result.

Notes

A cell with missing value on expression is assigned a missing value on Result.

Group

This operation belongs to the group of Arithmetic operators

Examples

  1. • pcrcalc
    binding
    Result = Result.map;
    Expr = Expr.map;
    initial
    report Result = atan(Expr);

    • python
    Expr = readmap(“Expr.map”)
    Result = atan(Expr)

    Result.map

    Expr.map
