  i know for integeers it use 32 bits
  hence there are 2^32 numbers that can represent integers
  
  but what about float and double??
  float is 32bit
  double is 64bit
  
  i only know 1 bit for the sign... then the rest i dunno liao...
  read the textbook liao but only say it is 32 bit and 64 bit, nv gif details
  
  [B]how does microsoft Visual C++ store float and double?? what are range of values that float and double can store???[/B]

  i hope this link is able to answer your question. To wat accuracy how MS Visual C++ stores or managed a float/double depends on the compiler which compiles your code, Operating System and hardware your using.

  unless your doing computer science or encryption, such knowledge is just nice to have and gd to know. Knowing how a programmng langauge actually compiles and executes a program will aid you in program design and efficiency.
