5.5.1 Definition of a range of values
The .. is an infixed operator
which sets a range of values; given two real numbers a and b,
the range of values between them is denoted a..b.
Remark.
Note that the order of the boundaries of the range
is significant. For example, if you input
then B and C are not equal; B==C returns
0.
Examples
Remark.
Since .. is an operator, the parts of an expression can be
picked out of it (see Section 7.2.3). In particular, the
left and right commands find the left and right
endpoints of a range (see Section 4.2.4, Section 7.2.3,
Section 5.6.2, Section 5.3.6, Section 8.2.4 and
Section 8.2.5 for other uses of left and right.)
For example:
