WebMar 22, 2011 · 20. The reason for float_t is that for some processors and compilers using a larger type e.g. long double for float could be more efficient and so the float_t allows the compiler to use the larger type instead of float. thus in the OPs case using float_t the change in size is what the standard allows for. If the original code wanted to use the ... WebSep 4, 2012 · On most systems today (including x86), the efficiency of float is not dependent on 32/64-bit.

WebA floating-point variable can represent a wider range of numbers than a fixed-point variable of the same bit width at the cost of precision. A signed 32-bit integer variable has a maximum value of 2 31 − 1 = 2,147,483,647, whereas an IEEE 754 32-bit base-2 floating-point variable has a maximum value of (2 − 2 −23) × 2 127 ≈ 3.4028235 ... WebFeb 6, 2024 · Float's precision allows it to store a value of up to 9 digits (7 real digits, +2 from decimal to binary conversion) Double, like the name suggests can store twice as much precision as a float. It can store up to 17 digits. (15 real digits, +2 from decimal to binary conversion) e.g. float x = 1.426; double y = 8.739437; WebFunction Pointers can have very different sizes, from 4 to 20 bytes on an x86 machine, depending on the compiler. So the answer is no - sizes can vary. Another example: take an 8051 program. It has three memory ranges and thus has three different pointer sizes, from 8 bit, 16 bit, 24 bit, depending on where the target is located, even though ... chinagardengf
