String <=

Description

Tests if the String on the left is less than or equal to the String on the right. This operator evaluate Strings in alphabetical order, on the first character where the two differ. So, for example "a" < "b" and "1" < "2", but "999" > "1000" because 9 comes after 1.

Caution: String comparison operators can be confusing when you're comparing numeric Strings, because the numbers are treated as Strings and not as numbers. If you need to compare numbers numerically, compare them as ints, floats, or longs, and not as Strings.

Syntax

myString1 <= myString2

Parameter Values

  • myString1: variable of type String.
  • myString2: variable of type String.

Return Values

  • true: If myString1 is less than or equal to myString2.
  • false: Otherwise.

※ NOTES AND WARNINGS:

If the string is modified, it is highly recommended using String.reserve() to prevent the memory fragmentation issue
