What is the difference between float and double? - Stack Overflow I've read about the difference between double precision and single precision However, in most cases, float and double seem to be interchangeable, i e using one or the other does not seem to affec
integer - What exactly is a float? - Stack Overflow This is the reason why we call them "floating point numbers" - we allow the decimal point to "float" depending on how big the number that we want to write is Let's give an example in decimal notation Suppose that you are given 5 cells to write down a number: _ _ _ _ _ If you don't use decimal points, then you can represent numbers from 0 to
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
java - What is the difference between the float and integer data type . . . float stores floating-point values, that is, values that have potential decimal places int only stores integral values, that is, whole numbers So while both are 32 bits wide, their use (and representation) is quite different You cannot store 3 141 in an integer, but you can in a float Dissecting them both a little further: In an integer, all bits except the leftmost one are used to store the
Difference between (float *) *(float*) in C - Stack Overflow casting to float * here is not meaningful, because the void * address is the same as the float * address and also the int * address, the difference would be when you do pointer arithmetic You are casting the int pointer to a float and dereferencing the resulting float pointer, although it will violate strict aliasing rules in c Copy
What is the point of float(inf) in Python? - Stack Overflow Just wondering over here, what is the point of having a variable store an infinite value in a program? Is there any actual use and is there any case where it would be preferable to use foo = float(
