英语词汇“absolute value”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

absolute value n. Mathematics (a) the value of a real number disregarding its sign; (b) (in relation to a complex number x + iy) the positive square root of x² + y²; cf. magnitude n. 2a(b), modulus n. 2e. [In sense (a) perhaps after French valeur absolue (1811 or earlier). With sense (b) compare German absoluter Betrag (in this sense, K. Weierstrass 1876, in Abhandl. der Königlich Preussischen Akad. der Wissensch. zu Berlin (Math. Klasse) 2; 1851 or earlier in sense (a)).]
