.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,
+integers). Each of the procedures takes a \fIsrc\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
+\fBTCL_OK\fR. If \fIsrc\fR does not have the proper syntax for the
+desired type then \fBTCL_ERROR\fR 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
+\fBTcl_GetInt\fR expects \fIsrc\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
+white space. If the first two characters of \fIsrc\fR
+after the optional white space and sign are
+.QW 0x
+then \fIsrc\fR is expected to be in hexadecimal form; otherwise,
+if the first such character is
+.QW 0
+then \fIsrc\fR
+is expected to be in octal form; otherwise, \fIsrc\fR is
expected to be in decimal form.
.PP
-\fBTcl_GetDouble\fR expects \fIstring\fR to consist of a floating-point
+\fBTcl_GetDouble\fR expects \fIsrc\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
+decimal point; a sequence of digits; the letter
+.QW e ;
+a signed decimal exponent; and more white space.
+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.
+and if the
+.QW 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,
+\fBTcl_GetBoolean\fR expects \fIsrc\fR to specify a boolean
+value. If \fIsrc\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,
+If \fIsrc\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.
