Plural of decimal: numbers expressed using the decimal point system where each position represents a power of ten.
From Latin 'decimus' (tenth). The decimal point notation was popularized by Scottish mathematician John Napier in the late 1600s, revolutionizing mathematics and science.
Ancient civilizations like the Babylonians actually used a base-60 system (why we still have 60 seconds in a minute), but decimals became universal because our ancestors happened to count on their ten fingers—our biology shaped human mathematics!
