ENDSUB
Type: Command
Description: Ending Sublist Command: Provides a way to access the total number of sublists contained in the
list used by DOSUBS.
Returns an Undefined Local Name error if executed when DOSUBS is not active.

LIST PROCEDURES ENDSUB
( °is the left-shift of the Nkey).
Input/Output: None
Example: The following program subtracts the number of elements in a list from each element in the list
« → a « a 1 « ENDSUB - » » DOSUBS »

ENG
Type: Command
Description: Engineering Mode Command: Sets the number display format to engineering mode, which
displays one to three digits to the left of the fraction mark (decimal point) and an exponent that is
a multiple of three. The total number of significant digits displayed is n + 1.
Engineering mode uses n + 1 significant digits, where 0 ≤ n ≤ 11. (Values for n outside this range
are rounded up or down.) A number is displayed or printed as follows:
(sign) mantissa
E
(sign) exponent
where the mantissa is of the form (nn)n.(n…) (with up to 12 digits total) and the exponent has one
to three digits.
A number with an exponent of –499 is displayed automatically in scientific mode.

Example: The number 103.6 in Engineering mode with five significant digits (n=4) would appear as
103.60E0. This same number with one significant digit (n=0) would appear as 100.E0.

EPSX0
Type: Function
Description: Replaces all coefficients in a polynomial that have an absolute value less than that held in the
CASDIR variable EPS, with 0. The default value of EPS is 1E-10, which can be changed by
storing a new number in the variable EPS in the CASDIR directory; this must be less than 1.
Access: Catalog, …µ
Input: A polynomial.
Output: The polynomial with conforming coefficients replaced with 0.
Flags: Exact mode must be set (flag –105 clear).
Numeric mode must not be set (flag –3 clear).
