WuV: slides claim a codec for floats to strings is easy

[ComFreek]

The IEEE 754-2008 standard revision does not state at all how floats are encoded/decoded from strings. Here's a PDF Google found for the otherwise closed-access standard. In fact, choosing a human-friendly string representation is a non-trivial research question, see https://stackoverflow.com/questions/7153979/algorithm-to-convert-an-ieee-754-double-to-a-string.
