or Catalog > BooleanExpr1 or BooleanExpr2 ⇒ Boolean expression Returns true or false or a simplified form of the original entry. Returns true if either or both expressions simplify to true. Returns false only if both expressions evaluate to false. Note: See xor. Note for entering the example: In the Calculator application @ on the handheld, you can enter multi-line definitions by pressing · instead of at the end of each line. On the computer keyboard, hold down Alt and press Enter. Integer1 or Integer2 ⇒ integer In Hex base mode: Compares two real integers bit-by-bit using an or operation. Internally, both integers are converted to signed, 64-bit binary numbers. When corresponding bits are compared, the result is 1 if either bit is 1; the result is 0 only if both bits are 0. The returned value represents the bit results, and is displayed according to the Base mode. Important: Zero, not the letter O. In Bin base mode: You can enter the integers in any number base. For a binary or hexadecimal entry, you must use the 0b or 0h prefix, respectively. Without a prefix, integers are treated as decimal (base 10). Note: A binary entry can have up to 64 digits (not counting the 0b prefix). A hexadecimal entry can have up to 16 digits. If you enter a decimal integer that is too large for a signed, 64-bit binary form, a symmetric modulo operation is used to bring the value into the appropriate range. For more information, see 4Base2, page 12. Note: See xor. ord( ) ord(String) ⇒ integer ord(List1) ⇒ list Returns the numeric code of the first character in character string String, or a list of the first characters of each list element. Catalog > P P4Rx( ) P4Rx(rExpr, qExpr) ⇒ expression P4Rx(rList, qList) ⇒ list P4Rx(rMatrix, qMatrix) ⇒ matrix In Radian angle mode: Returns the equivalent x-coordinate of the (r, q) pair. Note: The q argument is interpreted as either a degree, gradian or radian angle, according to the current angle mode. If the argument is an expression, you can use ¡, G or R to override the angle mode setting temporarily. Note: You can insert this function from the computer keyboard by typing P@>Rx(...).

P

BooleanExpr1
or
BooleanExpr2
⇒
Boolean expression
Returns true or false or a simplified form of the original entry.
Returns true if either or both expressions simplify to true. Returns
false only if both expressions evaluate to false.
Note:
See
xor
.
Note for entering the example:
In the Calculator application
on the handheld, you can enter multi-line definitions by pressing
@
instead of
·
at the end of each line. On the computer keyboard,
hold down
Alt
and press
Enter
.
Integer1
or
Integer2
⇒
integer
Compares two real integers bit-by-bit using an or operation.
Internally, both integers are converted to signed, 64-bit binary
numbers. When corresponding bits are compared, the result is 1 if
either bit is 1; the result is 0 only if both bits are 0. The returned value
represents the bit results, and is displayed according to the Base
mode.
You can enter the integers in any number base. For a binary or
hexadecimal entry, you must use the 0b or 0h prefix, respectively.
Without a prefix, integers are treated as decimal (base 10).
If you enter a decimal integer that is too large for a signed, 64-bit
binary form, a symmetric modulo operation is used to bring the value
into the appropriate range. For more information, see

In Hex base mode:
Important:
Zero, not the letter O.
In Bin base mode:
Note:
A binary entry can have up to 64 digits (not counting the
0b prefix). A hexadecimal entry can have up to 16 digits.

argument is interpreted as either a degree, gradian or
radian angle, according to the current angle mode. If the argument is
an expression, you can use

to override the angle mode
setting temporarily.
