About Percentage Calculator
Last updated: May 2026
Kalkulator Peratus OptiPix mengendalikan enam pengiraan peratus yang biasa. Cari apakah X% daripada Y, tentukan peratus X daripada Y, kira perubahan peratus antara dua nombor, tambah atau tolak peratus daripada nilai, dan hitung perbezaan peratus antara dua nilai. Setiap mod menunjukkan formula yang digunakan. Sejarah pengiraan menjejaki 10 hasil terakhir anda untuk rujukan mudah. Semua matematik berjalan secara tempatan di penyemak imbas anda tanpa panggilan pelayan.
How It Works
Setiap mod pengiraan menggunakan formula aritmetik yang mudah. Alat ini mengesahkan input untuk mengendalikan kes tepi seperti pembahagian dengan sifar dan memaparkan formula bersama hasil untuk ketelusan.
