Shouldn't ≥ also be an acceptable substitute for >=?

Question

A problem asked for setting up an if statement wherein it was looking for a value being greater than or equal to 180. As this was not a problem with a word/answer bank, I had to type in the correct symbol, but it did not accept ≥ as an answer. I ended up using bits to show the solution, which was >=.

Answer 1

Programmatical symbols are different than Mathematical symbols.

Answer 2

Each programming language has its own rules, syntax, grammar, keywords, operators.
In most cases, it is an important design principle that characters should be easy to type with a conventional keyboard.

There are some languages where symbols are quite unique and different.
For example, APL (literally meaning "A Programming Language") was designed in the 1950s as a mathematical notation, and later became an actual programming language.

And many similar languages emerged since, mostly in the array language family.

There are also some esoteric language that deal with symbols, like Emojicode

Or the language Piet uses colorful 2d images as the code itself.

Answer 3

>= are two characters, ≤ is a single character. The parser probably is not written to recognize the latter.
