Jan 26, 2011 · 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 …

Why do some numbers lose accuracy when stored as floating point numbers? For example, the decimal number 9.2 can be expressed exactly as a ratio of two decimal integers (92/10), both of which can be

For a given IEEE-754 floating point number X, if 2^E <= abs(X) < 2^(E+1) then the distance from X to the next largest representable floating point number (epsilon) is: epsilon = 2^(E-52) % For a 64-bit …

I want to print a float value which has 2 integer digits and 6 decimal digits after the comma. If I just use printf("%f", myFloat) I'm getting a truncated value. I don't know if this always happen...
