Relational operators

exp relational.operator exp

Relational operators are:

=

#

>=

<=

>

<

These operators first attempt to convert both operands into numerics. If successful, a numeric comparison is performed at the current precision. If unable to convert both operands into numerics, the operators convert both operands to strings and perform a left-to-right comparison.

The value returned is nonzero (true) or 0 (true).

The result is 0.

print 3 = 2

The result is nonzero because 2 was converted into a string that comes before the string "dog" in alphabetical order.

print 2 < "dog"

The result is nonzero (true). Although the first 3 characters of x are actually a string of characters, the = operator was able to successfully convert this into a number and do a numeric test for equality.

equ am to char(254)
x = "623abc"
print 623 = x[1,3]
