-# Number to Bytesize
+# Byte String
 
 Convert a number to a string that represents a rounded size in bytes.
 
 ## Example
 
 ```
-f(156833213) // => '156.83 MB'
-f('8101')    // => '8.1 kB'
-f(12331, 3)  // => '12.331 kB'
+f(156833213) // => "149.57 MB"
+f(8101)      // => "7.91 KB"
+f(12331, 3)  // => "12.042 KB"
 ```
