15.78.4.1 Errors
- The error is generated in a simple fashion. The computation is repeated for the value+err. For example you specify: TD:Y="SIN(YV)" then the result is: NDY=-(SIN(Y-DY)-SIN(Y)) DY=SIN(Y+DY)-SIN(Y) Y=SIN(Y) This computation may not be correct, so the error analysis must be carefully checked. It will work for many simple cases.
