Converts a $DOUBLE floating point number to an eight-byte string.
||An IEEE-format floating point number. It can be specified as a value, a variable, or an expression.
returns an eight-byte (quad) character string corresponding to n
. The bytes of the character string are presented in little-endian byte order, with the least significant byte first.
The number n
can be a positive or negative IEEE floating point number. If n
is not numeric, $ZDCHAR
returns the empty string. For further details on IEEE floating point numbers, refer to the $DOUBLE
The following examples return an eight-byte string corresponding to the IEEE floating point number:
These two functions return: "ffffffö?" and "kfffffö?"
$ZDCHAR and Other $CHAR Functions
converts an IEEE floating point number to a eight byte (64-bit) character string. $ZQCHAR
converts an integer to an eight byte (64-bit) character string. To convert an integer to an 8-bit character string use $CHAR
. To convert an integer to a 16-bit (wide) character string use $ZWCHAR
. To convert an integer to a 32-bit (long) character string use $ZLCHAR
