				.Nm Q_IRAWMASK ,
				.Nm Q_GIRAW ,
				.Nm Q_GIABSVAL ,
				.Nm Q_GIVAL ,
				.Nm Q_SIVAL
				.Nd fixed-point math functions which manipulate the integer data bits
				.Sh SYNOPSIS
				.In sys/qmath.h
				.Ft ITYPE
				.Fn Q_IRAWMASK "QTYPE q"
				.Ft ITYPE
				.Fn Q_GIRAW "QTYPE q"
				.Ft ITYPE
				.Fn Q_GIABSVAL "QTYPE q"
				.Ft ITYPE
				.Fn Q_GIVAL "QTYPE q"
				.Ft QTYPE
				.Fn Q_SIVAL "QTYPE q" "ITYPE iv"
				.Sh DESCRIPTION
				.Fn Q_IRAWMASK
				returns a
				.Fa q Ns -specific
				bit mask for
				.Fa q Ap s
				integer data bits.
				.Pp
				.Fn Q_GIRAW
				returns
				.Fa q Ap s
				raw masked integer data bits.
				.Pp
				.Fn Q_GIABSVAL
				and
				.Fn Q_GIVAL
				return the absolute and real values of
				.Fa q Ap s
				integer data bits respectively.
				.Pp
				.Fn Q_SIVAL
				sets
				.Fa q Ap s
				integer data bits to the value
				.Fa iv .
				.Pp
				All of those functions operate on
				the following data types:
				.Vt s8q_t ,
				.Vt u8q_t ,
				.Vt s16q_t ,
				.Vt u16q_t ,
				.Vt s32q_t ,
				.Vt u32q_t ,
				.Vt s64q_t ,
				and
				.Vt u64q_t ,
				which are referred to generically as
				.Fa QTYPE .
				The
				.Fa ITYPE
				refers to the
				.Xr stdint 7
				integer types.
				.Pp
				For more details, see
				.Xr qmath 3 .
				.Sh RETURN VALUES
				.Fn Q_IRAWMASK ,
				.Fn Q_GIRAW ,
				.Fn Q_GIABSVAL
				and
				.Fn Q_GIVAL
				return their respective values as integers of the same underlying ITYPE as
				.Fa q .
				.Pp
				.Fn Q_SIVAL
				returns the value of
				.Fa q
				post change.
