The less-than sign with the equals sign, <=, may be used for an approximation of the less-than-or-equal-to sign, ≤. ASCII does not have a less-than-or-equal-to sign, but Unicode defines it at code point U+2264. In BASIC, Lisp-family languages, and C-family languages (including Java and C++), operator <= means "less than or equal to".
In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. [1] It is used most often to compare two numbers on the number line by their size. The main types of inequality are less than (<) and greater than (>).
The equals sign (British English) or equal sign (American English), also known as the equality sign, is the mathematical symbol =, which is used to indicate equality in some well-defined sense. [1] In an equation , it is placed between two expressions that have the same value, or for which one studies the conditions under which they have the ...
An alternative notation for this usage is to typeset the letters "def" above an ordinary equality sign, =. [14] Similarly, another alternative notation for this usage is to precede the equals sign with a colon, :=. The colon notation has the advantage that it reflects the inherent asymmetry in the definition of one object from already defined ...

A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...
where ⌊ x ⌋ is the floor function, which denotes the greatest integer less than or equal to x and the p i run over all primes ≤ √ x. [1] [2] Since the evaluation of this sum formula becomes more and more complex and confusing for large x, Meissel tried to simplify the counting of the numbers in the Sieve of Eratosthenes. He and Lehmer ...
Programming in the small can involve programming by individuals or small groups over short time periods and may involve less formal practices (for instance less emphasis on documentation or testing), tools and programming languages (e.g. the selection of a loosely typed scripting language in preference to a strictly typed programming language).
