Line 17:

The format is written with an implicit lead bit with value 1 unless the exponent is all zeros. Thus only 236 bits of the [[significand]] appear in the memory format, but the total precision is 237 bits (approximately 71 decimal digits: {{nowrap|log₁₀(2²³⁷) ≈ 71.344}}).

<!-- (Commented out since the image is incorrect; it could be re-added once corrected.)-->

The bits are laid out as follows:

The bits are laid out as follows (as you can see, it is so super-massive that it goes off the page, thus this visually demonstrates that common implementation of this would produce lots of lag):
