Add two double values treating NaN as 0 if one side is a number.

Boolean greater than of two doubles treating NaN as smaller if one side is a number.

Check if a double value is nearly zero, i.e., within a small amount from 0. For our purposes the small amount is 1e-12. Not sure of the original reason for choosing that amount, but it has been used for a long time.

Find the max of two double values treating NaN as smaller if one side is a number.

Find the min of two double values treating NaN as smaller if one side is a number.

Subtract two double values treating NaN as 0 if one side is a number.
