Tabel logaritma merupakan tabel yang memuat [[logaritma umum]], atau logaritma dengan bilangan pokok 10. Tabel ini dipakai dengan luas dalam computations prior to the advent of electronic calculators and computers because logarithms convert problems of multiplication and division into much easier addition and subtraction problems. Base-10 logarithms have an additional property that is unique and useful: The common logarithm of numbers greater than one that differ only by a factor of a power of ten all have the same fractional part, known as the ''mantissa''. Tables of common logarithms typically included only the [[Significand|mantissas]]; the integer part of the logarithm, known as the ''characteristic'', could easily be determined by counting digits in the original number. A similar principle allows for the quick calculation of logarithms of positive numbers less than 1. Thus a single table of common logarithms can be used for the entire range of positive decimal numbers.<ref>E. R.

Tabel matematika adalah tabel yang memperlihatkan hasil perhitungan dengan berbagai nilai argumen, dengan menulis daftar bilangan-bilangan.

Tabel yang pertama kali dibuat adalah tabel trigonometri, sebuah tabel yang dipakai orang Yunani Kuno. Tabel ini mempunyai penerapan terkait astronomi and navigasi benda angkasa. Tabel ini kemudian dipakai lebih luas hingga kehadiran kalkulator elektronik yang memiliki fungsi menyederhanakan dan mempercepat perhitungan. Selain itu, tabel logaritma dan tabel fungsi trigonometri merupakan tabel yang umumnya terdapat di dalam buku cetak matematika dan ilmu pengetahuan, dan tabel-tabel khusus yang diterbitkan dipakai untuk berbagai penerapan di bidang lain.

Tabel logaritma

Tabel logaritma merupakan tabel yang memuat logaritma umum, atau logaritma dengan bilangan pokok 10. Tabel ini dipakai dengan luas dalam computations prior to the advent of electronic calculators and computers because logarithms convert problems of multiplication and division into much easier addition and subtraction problems. Base-10 logarithms have an additional property that is unique and useful: The common logarithm of numbers greater than one that differ only by a factor of a power of ten all have the same fractional part, known as the mantissa. Tables of common logarithms typically included only the mantissas; the integer part of the logarithm, known as the characteristic, could easily be determined by counting digits in the original number. A similar principle allows for the quick calculation of logarithms of positive numbers less than 1. Thus a single table of common logarithms can be used for the entire range of positive decimal numbers.[1] See common logarithm for details on the use of characteristics and mantissas.
