CIMU.CRCGridInexact Method

Computes a CRC Checksum on a grid and allows you to specify number of bits of floats/doubles to drop so that the CRC will be same even of this are changed.

Available since Oasis montaj version: 5.0
License: Available to anyone.

Namespace: GeoEngine.Core.GXNetX
Assembly: geoengine.core.gxnetx (in geoengine.core.gxnetx.dll)

Notes

Very useful for testing where the last bits of accuracy are not as important.
