Usage

Syntax

Float (in_raster_or_constant)
ParameterExplanationData Type
in_raster_or_constant

The input raster to be converted to floating point.

In order to use a number as an input for this parameter, the cell size and extent must first be set in the environment.

Raster Layer | Constant

Return Value

NameExplanationData Type
out_raster

The output raster.

The cell values are the floating-point representation of the input values.
