Relational operators

Relational operators are used to compare both strings and/or numerics.

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).

Note: These strings are considered nonnumeric only when used with the above relational operators: ".", "+", "-", "-.", "+.", and "".


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]
