Lemme Go With Fixed Point

Lemme Go With Fixed Point
Floating point arithmetic: where 0.1 + 0.2 = 0.30000000000000004 but 0.2 + 0.3 = 0.5 exactly. It's like your computer is secretly trolling you with binary representation limitations while pretending to understand decimal math. The mental breakdown with math equations plastered everywhere is the perfect visualization of a developer's soul after spending 3 hours debugging what should be simple arithmetic. Fixed point looking real attractive right now...

Turns Out Floats Are Just Structs

Turns Out Floats Are Just Structs
The code reveals floating point numbers for what they truly are: just fancy structs with a sign, exponent, and mantissa wearing a trench coat. The programmer manually constructs a float by setting each field, then casts it back to a float with that sketchy pointer manipulation. And of course, there's the mandatory comment warning you to never actually do this in production because bitfield layout will betray you faster than a coworker who "fixed" your code. Typical C behavior - giving you enough rope to not only hang yourself but the entire dev team.

Stop Doing NaNs

Stop Doing NaNs
Ah, the eternal JavaScript nightmare: NaN (Not a Number) - which ironically is a number type that doesn't equal itself. Because that makes perfect sense! The IEEE 754 floating-point standard really outdid itself here. "Let's create a special value that represents calculation errors but make it behave in the most counterintuitive ways possible!" My favorite part is JavaScript trying to be helpful: "You want to convert 'hello' to a number? Sure thing! Here's a NaN for your trouble. No errors thrown, just silent mathematical chaos." And then we wonder why our date calculations suddenly think it's the year NaN. The hex(983061) at the bottom is the cherry on top - it's 0xF00D61, or "FOOD A1". Even the hexadecimal is trolling us.
