Syntax
BIN(intA,intB{,ERR=lineref})
Description
For BBj-specific information, see the BBj BIN()
Function.
The BIN() function converts a decimal into a binary string.
|
Parameter |
Description |
|---|---|
|
intA |
Decimal to be converted into a binary string. The left-most bit is considered the "sign" bit. If it is "on" (1), the number is negative. Negative numbers are stored in two's complement (negative binary) notation. |
|
IntB |
Length of the binary string, in bytes. |
|
ERR=lineref |
Branch to be taken if an error occurs during execution. |
Although BIN() returns a signed binary string, an overflow error is
issued only if an unsigned overflow occurs. For example, BIN(255,1) and
BIN(-1,1) both return $FF$ without an error.
The DEC() function performs the reverse
operation of BIN(). However, DEC() always assumes a signed binary value.
DEC(BIN(255,1)) returns -1.
