|Command||basic.relational.operators Relational Operator/BASIC Program
Applicable release versions: AP, R83
|Category||BASIC Program (486)|
|Description||used to compare both strings and/or numerics.
The relational operators are:
=, #, >=, <=, >, and <
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 will be non-zero (true) or zero (true).
|Syntax||expression relational.operator expression|
1) print 3 = 2 The result is a 0. 2) print 2 < "dog" The result is non-zero because 2 was converted into a string which comes before the string "dog" in alphabetical order. 3) equ am to char(254) x = "623abc" print 623 = x[1,3] The result is non-zero (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.
