The inverse of a logarithm, for when you want your exponent back.
means The inverse operation of taking a logarithm — given a logarithm's value, the antilog finds the original number it came from.
from A 20th-century mathematical shorthand, built from 'anti-' (against/opposite) plus 'log,' itself clipped from 'logarithm' — a word coined in the 1610s from Greek 'logos' (ratio, reckoning) and 'arithmos' (number). Antilog simply marks the reverse trip: if a logarithm turns a number into an exponent, the antilog turns that exponent back into the number.
