Flags Used:
None.
Remarks:
The accuracy of this program is dependent on the display setting. For inputs in the
area between ±3 standard deviations, a display of four or more significant figures
is adequate for most applications.
At full precision, the input limit becomes ±5 standard deviations. Computation time
is significantly less with a lower number of displayed digits.
In routine Q, the constant 0.5 may be replaced by 2 and
.
You do not need to key in the inverse routine (in routines I and T) if you are not
interested in the inverse capability.
