Floating-point will quietly corrupt your emissions math, and 0.1 + 0.2 already warned you
⚡ TL;DR · AI summary

Floating-point arithmetic can lead to significant errors in emissions calculations, particularly when reconciling totals. A common example is the discrepancy seen in the sum of 0.1 and 0.2, which results in 0.30000000000000004 instead of the expected 0.3. This issue becomes critical in emissions accounting, where exact figures are necessary for audits and compliance.
