Ranges of floating point datatype in C? - Stack Overflow The values for the float data type come from having 32 bits in total to represent the number which are allocated like this: 1 bit: sign bit 8 bits: exponent p 23 bits: mantissa The exponent is stored as p + BIAS where the BIAS is 127, the mantissa has 23 bits and a 24th hidden bit that is assumed 1 This hidden bit is the most significant bit (MSB) of the mantissa and the exponent must be
How to correctly and standardly compare floats? - Stack Overflow Note that float can approximately represent the latter and still smaller values - it's just about 7 decimals of precision after the first nonzero digit! If you're going to use a fixed epsilon, you should really choose it according to the requirements of the particular piece of code where you use it
