log1p()
Java Math log1p() metodi
Misol
x ning turli qiymatlari uchun 1 + x ning natural logarifmini qaytaring:
System.out.println(Math.log1p(6));
System.out.println(Math.log1p(Math.E));
System.out.println(Math.log1p(2));
System.out.println(Math.log1p(1));
System.out.println(Math.log1p(0));
System.out.println(Math.log1p(-1));
Ta’rif va qo‘llanilishi
log1p() metodi istalgan x soni uchun 1 + x ning natural logarifmini qaytaradi.
Natural logarifm — e asosli logarifm. e qiymati taxminan 2.718282 ga teng bo‘lib, Java tilida u Math.E konstantasi sifatida mavjud.
