mathematical concept; value which cannot be changed or does not change during a process
A constant is a value in mathematics that stays the same and doesn't change, unlike a variable which can take on different values. Constants matter because they serve as reliable, unchanging reference points that help us describe and solve mathematical problems accurately.

常数，又稱定數（英語：Constant），是指一个数值固定不变的常量，例如圆周率、自然对数的底，与之相反的是變數。在物理學上，很多經測量得出的數值都被稱為常數。例如萬有引力常數和地表重力加速度等。但有研究表明，部分這類常数并不是恒定不变的，因此就被稱作“”（inconstant constant）和“”（not-so-constant constant）。
