Welcome to the digital hellscape where 0.7 × 0.7 = 0.49 in theory but 0.48999999999994 in practice. This is the programmer's nightmare that makes mathematicians weep. Computers store decimal numbers in binary, and some decimals just can't be represented exactly—like trying to write 1/3 as a decimal without going on forever. The computer is technically correct (the worst kind of correct) because it's showing you all those hidden digits that round-off arithmetic hides. Next time your bank account is off by a penny, remember it's not a glitch—it's just floating point arithmetic having an existential crisis.
