- Float and Int Both 4 Bytes? How Come?While a 32-bit float can represent numbers of greater magnitude than a 32-bit int, it cannot represent all of them with as much precision. In total, this answer derives that a 32-bit float can represent around 4,278,190,081 unique numbers. This other answer contains a nice plot showing how these 32-bit floats are distributed on the real line.
- How to use % operator for float values in c - Stack Overflowconsider : int 32 bit and long long int of 64 bits. Yes, %(modulo) operator isn't work with floats and double.. if you want to do the modulo operation on large number you can check long long int(64bits) might this help you.
- What is the difference between float and double? - Stack OverflowAs the name implies, a double has 2x the precision of float [1]. In general a double has 15 decimal digits of precision, while float has 7. Here's how the number of digits are calculated: double has 52 mantissa bits + 1 hidden bit: log(2 53)÷log(10) = 15.95 digits. float has 23 mantissa bits + 1 hidden bit: log(2 24)÷log(10) = 7.22 digits
- What are the actual min/max values for float and double (C++)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.
