Detailed Description
This is useful for (for example) showing the range of visible lines. A double-precision value has 53 significant bits in the mantissa - so we would start to have precision problems at the high end of the range we can represent. Long double has a 64 bit mantissa on Intel, which means that we would start to run into trouble at the very very end of our range - barely acceptable.
