.SH DESCRIPTION
|
||||
The
|
||||
.BR lsaneglue
|
||||
library contains code to let you call SANE functions directly from ORCA/C.
|
||||
To avoid namespace conflicts with
|
||||
.IR <math.h> ,
|
||||
it was necessary to change
|
||||
.IR <sane.h> .
|
||||
Thus, all SANE functions are now prefixed with
|
||||
.BR s_ .
|
||||
(For example,
|
||||
.BR annuity
|
||||
became
|
||||
.BR s_annuity ,
|
||||
and
|
||||
.BR sin
|
||||
became
|
||||
.BR s_sin .)
|
||||
This lets you choose easily between the SANE and ISO/C implementations of
|
||||
the same function.
|
||||
.LP
|
||||
Below is a brief overview of the functions in
|
||||
.BR lsaneglue .
|
||||
This overview does not replace, however, proper documentation. To fully
|
||||
understand SANE, you will need the
|
||||
.IR "Apple Numerics Manual".
|
||||
SANE is also introduced in the
|
||||
.IR "Apple IIgs Toolbox Reference" ,
|
||||
Volume 2", Chapter 18.
|
||||
.LP
|
||||
It is important that the file
|
||||
.IR <sane.h>
|
||||
is used as the reference for constants used for
|
||||
rounding direction, rounding precision, number classes, ordering relations,
|
||||
formatting styles, NaN codes, and for settine and testing exceptions,
|
||||
.LP
|
||||
In the following list, page numbers refer to the
|
||||
.IR "Apple Numerics Manual" .
|
||||
.IP \fBfindfpcp\fR
|
||||
This function is specific to the
|
||||
.BR lsaneglue
|
||||
library; it is not part of SANE proper and is not documented elsewhere.
|
||||
.sp 1
|
||||
.BR findfpcp
|
||||
will find an FPE (Innovative Systems' Floating Point Engine)
|
||||
or NC (Number Cruncher) card and return the slot number in which it resides.
|
||||
If a card is not found, it will return
|
||||
.BR -1 .
|
||||
.sp 1
|
||||
You can use the output of this function as the argument for the ORCA/C
|
||||
.BR setfpeslot (3)
|
||||
routine, which is used when having ORCA/C create code for the FPE/NC
|
||||
directly (through the directive
|
||||
.BR "#pragma float 1 1" ).
|
||||
.IP \fBs_num2dec\fR
|
||||
Converts extended number
|
||||
.IR x
|
||||
to a SANE decimal record,
|
||||
.IR I .
|
||||
(pp 28)
|
||||
.IP \fBs_dec2num\fR
|
||||
Converts SANE decimal record
|
||||
.IR f
|
||||
to an extended number. (pp 28f)
|
||||
.IP \fBs_str2dec\fR
|
||||
Converts string
|
||||
.IR s
|
||||
to a SANE decimal record,
|
||||
.IR d .
|
||||
(pp 30f)
|
||||
.IP \fBs_dec2str\fR
|
||||
Convert a SANE decimal record
|
||||
.IR d
|
||||
to a string.
|
||||
(pp 31ff)
|
||||
.IP \fBs_fabs\fR
|
||||
Returns the absolute value of
|
||||
.IR x .
|
||||
(pp 49)
|
||||
.IP \fBs_fneg\fR
|
||||
Reverses the sign of
|
||||
.IR x .
|
||||
(pp 49)
|
||||
.IP \fBs_remainder\fR
|
||||
Returns the remainder
|
||||
.IR "x / y" .
|
||||
(pp 46f)
|
||||
.IP \fBs_sqrt\fR
|
||||
Returns the square root of
|
||||
.IR x .
|
||||
(pp 46)
|
||||
.IP \fBs_rint\fR
|
||||
Round
|
||||
.IR x
|
||||
to integer in current rounding direction. (pp 47)
|
||||
.IP \fBs_scalb\fR
|
||||
Returns (\fIx\fR times 2^\fIn\fR). (pp 50)
|
||||
.IP \fBs_logb\fR
|
||||
Computes binary exponent of normalized
|
||||
.IR x .
|
||||
(pp 50)
|
||||
.IP \fBs_copysign\fR
|

.SH "SANE TOOLKIT ERRORS"
|
||||
The fclass functions should return the sign of the passed number
|
||||
in n-bit and Y. They do not report the sign at all, though, which
|
||||
has to be considered a bug.
|
||||
.BR s_signnum
|
||||
has been rewritten to not rely on fclassx any more.
