{{fbdoc item="title" value="BITSET"}}----
Gets the value of an integer with a specified bit set.

{{fbdoc item="syntax"}}##
	[[KeyPgPpdefine #define]] **Bitset**( //value//, //bit_number// ) ((//value//) [[KeyPgOpOr or]] ([[KeyPgCast Cast]]([[KeyPgTypeof TypeOf]](//Value//), 1) [[KeyPgOpShiftLeft shl]] (//bit_number//)))
##
{{fbdoc item="usage"}}##
	//result// = **Bitset**( //value//, //bit_number// )
##
{{fbdoc item="param"}}
	##//value//##
		The integer value.
	##//bit_number//##
		The index of the bit to set.

{{fbdoc item="ret"}}
	Returns the integer value with the specified bit set.

{{fbdoc item="desc"}}
	This macro expands to a copy of the integer ##//value//## with the specified ##//bit_number//## set (to //on//, or `##1##`). Behaves as `##//value// [[KeyPgOpOr Or]] (1 [[KeyPgOpShiftLeft Shl]] //bit_number//)##`.

	The valid range of values for ##//bit_number//## depends on the size, in bits, of `##[[KeyPgTypeof Typeof]](//value//)##`, which is `##0##` through `##[[KeyPgSizeof Sizeof]](//value//) * 8 - 1##`. See [[TblVarTypes Standard Datatype Limits]] for a table of the standard datatypes and their sizes.
