Math Options

Grid + Constant:  Add a specified constant to every Grid node.

Grid + Grid: Add the corresponding node values from another Grid.  Example: Add two thickness Grids to output total thickness values.

Grid – Constant:  Subtract a specified constant from every node.

Constant – Grid:  Subtract every node value from a constant value.

Grid – Grid:  Subtract the corresponding node values from another Grid. Example: Subtract a lower surface grid from an upper grid to output thickness values.

Grid x Constant:  Multiply every node by a specified constant.

Grid x Grid:  Multiply every node by the corresponding node value within another Grid. Example: Multiply a Grid with a Boolean Grid (containing 0's and 1's) to zero-out areas where defined criteria are not met.

Grid / Constant:  Divide every node by a specified constant.  If the Constant value equals zero, C will equal zero.

Constant / Grid:  Divide a constant by every node value.

Grid / Grid:  Divide every node by the corresponding node value within another Grid.  If the B value equals zero, C will equal zero (i.e., no divide-by-zero error).  Example: Divide an ore thickness grid by an overburden thickness grid to create a stripping ratio Grid.

Absolute:  Convert all node values to their absolute values.

Average:  Compute the average for nodes within two Grids.  Example: Compute average hydrothermal temperatures between two different dates.

Difference:  Compute the difference between two Grids by computing the absolute value of subtracted nodes.

Highest:  If A > B then Result = A else Result = B.

Lowest:  If A < B then Result = A else Result = B.

Boolean AND:  If A = 1 & B = 1 then Result = 1 else Result = 0.  Only applies to Boolean Grids.

Boolean OR:  If A = 1 or B = 1 then Result = 1 else Result = 0.  Only applies to Boolean Grids.

Boolean XOR:  If A <> B then Result = 1 else Result = 0.  Only applies to Boolean Grids.
