Fun Fact
Most programming languages generate random decimal numbers by first producing a random integer behind the scenes, then scaling it into a fractional range-meaning decimals are often "disguised integers."
Historical Context
Decimal numbers became widely adopted after Simon Stevin's work in the late 16th century, which formalized decimal fractions for everyday arithmetic. In computing, random decimal generation evolved alongside pseudo-random number generators in the mid-20th century, enabling simulations, scientific modeling, and modern software testing.
