.SH DESCRIPTION
.PP
These procedures convert from strings to integers or double-precision
floating-point values or booleans (represented as 0- or 1-valued
integers).  Each of the procedures takes a \fIstring\fR argument,
converts it to an internal form of a particular type, and stores
the converted value at the location indicated by the procedure's
third argument.  If all goes well, each of the procedures returns
TCL_OK.  If \fIstring\fR doesn't have the proper syntax for the
desired type then TCL_ERROR is returned, an error message is left
in the interpreter's result, and nothing is stored at *\fIintPtr\fR
or *\fIdoublePtr\fR or *\fIboolPtr\fR.
.PP
\fBTcl_GetInt\fR expects \fIstring\fR to consist of a collection
of integer digits, optionally signed and optionally preceded by
white space.  If the first two characters of \fIstring\fR are ``0x''
then \fIstring\fR is expected to be in hexadecimal form;  otherwise,
if the first character of \fIstring\fR is ``0'' then \fIstring\fR
is expected to be in octal form;  otherwise, \fIstring\fR is
expected to be in decimal form.
.PP
\fBTcl_GetDouble\fR expects \fIstring\fR to consist of a floating-point
number, which is:  white space;  a sign; a sequence of digits;  a
decimal point;  a sequence of digits;  the letter ``e'';  and a
signed decimal exponent.  Any of the fields may be omitted, except that
the digits either before or after the decimal point must be present
and if the ``e'' is present then it must be followed by the
exponent number.
.PP
\fBTcl_GetBoolean\fR expects \fIstring\fR to specify a boolean
value.  If \fIstring\fR is any of \fB0\fR, \fBfalse\fR,
\fBno\fR, or \fBoff\fR, then \fBTcl_GetBoolean\fR stores a zero
value at \fI*boolPtr\fR.
If \fIstring\fR is any of \fB1\fR, \fBtrue\fR, \fByes\fR, or \fBon\fR,
then 1 is stored at \fI*boolPtr\fR.
Any of these values may be abbreviated, and upper-case spellings
are also acceptable.

298	\fBTcl_GetDouble\fR expects \fIstring\fR to consist of a floating-point
299	number, which is: white space; a sign; a sequence of digits; a
300	decimal point; a sequence of digits; the letter ``e''; and a
301	signed decimal exponent. Any of the fields may be omitted, except that
302	the digits either before or after the decimal point must be present
303	and if the ``e'' is present then it must be followed by the
304	exponent number.

306	\fBTcl_GetBoolean\fR expects \fIstring\fR to specify a boolean
307	value. If \fIstring\fR is any of \fB0\fR, \fBfalse\fR,
308	\fBno\fR, or \fBoff\fR, then \fBTcl_GetBoolean\fR stores a zero
309	value at \fI*boolPtr\fR.
310	If \fIstring\fR is any of \fB1\fR, \fBtrue\fR, \fByes\fR, or \fBon\fR,
311	then 1 is stored at \fI*boolPtr\fR.
312	Any of these values may be abbreviated, and upper-case spellings
313	are also acceptable.
