Embedded software is a reference to software written to work in a piece of hardware equipment. At first, this was code written directly for a specialized processor such as an FPGA or a DSP. Today, regular computers will be used for applications such as a medical device or a kiosk and it is also called embedded software, even though these just are desktop applications...
float is a type in most software languages referencing an IEEE floating point number. These numbers are generally defined on 32 or 64 bits with three parts: a sign, an exponent and a mantissa. There is also a bias which is not saved in the number. The sign is 0 (positive) or 1 (negative). This means you have a representation of: +0.0 and -0.0. The exponent is about 1/6th the total size in bits. The bias is added/subtracted from the exponent. In the end, it is a signed power of 2 exponent (i.e. exercises a shift on the mantissa.) The mantissa forms the current number.
nop is the usual abbreviation for the No Operation command often used in assembly language (processor code.) Some times, it is written as noop instead.
