number, which is: white space; a sign; a sequence of digits; a
-decimal point; a sequence of digits; the letter

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
-.QW e
-is present then it must be followed by the exponent number.

+are no fields apart from the sign and initial sequence of digits
+(i.e., no decimal point or exponent indicator), that
+initial sequence of digits should take one of the forms that
+\fBTcl_GetInt\fR supports, described above. The use of
+.QW \fB,\fR
+as a decimal point is not supported nor should any other sort of
+inter-digit separator be present.
