 Using a calculator and some basic algebra, we can find the $epsilon$ this code uses: \
 #note[Remember, #text[`0x5f3759df`] is $6240089$ in hexadecimal.]
 $
-  (3 times 2^22) (127 - epsilon) &= 6240089 \
-  (127 - epsilon) &= 126.955 \
-  epsilon &= 0.0450466
+  (3 times 2^22) (127 - epsilon) & = 6240089 \
+                 (127 - epsilon) & = 126.955 \
+                         epsilon & = 0.0450466
 $

 So, $0.045$ is the $epsilon$ used by Quake. \
