A particular embedded 'C' software uses FLOAT and DOUBLE.  

The range and scalings for FLOAT and DOUBLE values are defined in ANSI / IEEE Std 754.  How can I access and understand this information?

How to access ANSI/IEEE Std 754 or equivalent information ?

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.

In addition to ignition, power and monitoring gauges and lights, today's motor vehicles feature computerized engines, transmissions and braking systems, electronic mapping systems, Bluetooth and Internet connectivity, sensors that detect other vehicles, motorized seats, and digital audio and video systems; several manufacturers are producing electric and hybrid automobiles and self-driving cars.
