literal constant
In programming, a value written directly in source code, such as 42 or "hello", as opposed to a named constant or variable.
In this code, the number 100 is written directly as a literal constant.
Often used interchangeably with 定数表現 in programming contexts, but リテラル is a more common loanword for 'literal'.
Refers to a named constant (e.g., a variable declared with const), while 定数表現 specifically means a literal value written directly in code.
Compound of 定数 (constant) and 表現 (expression), likely a calque from English 'literal constant' used in computing.
