acos¶

acos

Inverse cosine

Result = acos(expression)

expression
spatial, non spatial scalar
Result
dimension of expression direction

Options¶

affects Result only if expression is a number:

--degrees
direction is given in degrees (default)

Operation¶

This operator calculates for each cell the inverse cosine of the cell value on expression and assigns it to Result.

Notes¶

The values on expression must be equal to or between -1 and 1. Cells with a value outside this range will be assigned a missing value on Result. 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
#! –degrees
binding
Result = Result.map;
Expr = Expr.map;
initial
report Result = acos(Expr);

• python
setglobaloption(“degrees”)
