The following functions produce binary strings from a number returned by an expression prefix. These functions are particularly useful in the TCP rewrite feature as replacement strings for binary data. For more information about the TCP rewrite feature, see Rewrite.

All the functions return a value of type text. The endianness that some of the functions accept as a parameter is either LITTLE_ENDIAN or BIG_ENDIAN.

Function	Description
.SIGNED8_STRING	Produces an 8-bit signed binary string representing the number. If the value is out of range, an undef condition is raised. Example: HTTP.REQ.BODY(100).GET_SIGNED8(16).SUB(3).SIGNED8_STRING
.UNSIGNED8_STRING	Produces an 8-bit unsigned binary string representing the number. If the value is out of range, an undef condition is raised. Example: HTTP.REQ.BODY(100).GET_UNSIGNED8(31).ADD(3).UNSIGNED8_STRING
.SIGNED16_STRING()	Produces a 16-bit signed binary string representing the number. If the value is out of range, an undef condition is raised. Example: HTTP.REQ.BODY(100).SKIP(12).GET_SIGNED16(0, BIG_ENDIAN).SUB(4).SIGNED16_STRING(BIG_ENDIAN)
.UNSIGNED16_STRING()	Produces a 16-bit unsigned binary string representing the number. If the value is out of range, an undef condition is raised. Example: HTTP.REQ.BODY(100).GET_UNSIGNED16(47, LITTLE_ENDIAN).ADD(7).UNSIGNED16_STRING(LITTLE_ENDIAN)
.SIGNED32_STRING()	Produces a 32-bit signed binary string representing the number. Example: HTTP.REQ.BODY(100).AFTER_STR(“delim”).GET_SIGNED32(0, BIG_ENDIAN).SUB(1).SIGNED32_STRING(BIG_ENDIAN)
.UNSIGNED8_STRING	Produces an 8-bit unsigned binary string representing the number. If the value is out of range, an undef condition is raised. Example: HTTP.REQ.BODY(100).GET_UNSIGNED8(24).TYPECAST_UNSIGNED_LONG_AT.ADD(12).UNSIGNED8_STRING
.UNSIGNED16_STRING()	Produces a 16-bit unsigned binary string representing the number. If the value is out of range, an undef condition is raised. Example: HTTP.REQ.BODY(100).GET_UNSIGNED16(23, LITTLE_ENDIAN).TYPECAST_UNSIGNED_LONG_AT.ADD(10).UNSIGNED16_STRING(LITTLE_ENDIAN)
.UNSIGNED32_STRING()	Produces a 32-bit unsigned binary string representing the number. If the value is out of range, an undef condition is raised. Example: HTTP.REQ.BODY(100).AFTER_STR(“delim2”).GET_UNSIGNED32(0, BIG_ENDIAN).ADD(2).UNSIGNED32_STRING(BIG_ENDIAN)
