DELTA tests whether
two numbers are equal
with a numeric result.
ERF Use the ERF function to return the integrated error function between a lower and upper limit.
The ERF function is found only if the Analysis-Toolpak is installed. In addition it must be
turned on in the Add-Ins from the Tools menu. Notice the example in Figure 5.13. The
lowerbound limit in the first example is 2 and the upper-bound limit is 3. The error result is .0047.
The numeric lower-bound for integrating the function.
The numeric upper-bound for integrating the function.
The equations are as follows:
Returns the integrated
error function for upper
and lower-bound limits.
