max precision in float
Hi,
As all of us know that size of int is machine as well as compiler dependent
we can get the range and size of an int , float and char etc in
/usr/include/limits.h
header file of a compiler
but could any one tell me how to get info of precision of float and double
data type in a perticular compiler ?
thanks

Hi,
I search a unix utility to diff two files, that takes as argument numerical precision as well. If two files are different only in numbers and the difference is less than precision then the result as they are the same.
The precision may be absolute (x1-x2) or relative (x2/x1). Also I need the... (1 Reply)

INTERCAL::ByteCode(3pm) User Contributed Perl Documentation INTERCAL::ByteCode(3pm)
TITLE
Language::INTERCAL::Bytecode - intermediate language
DESCRIPTION
The CLC-INTERCAL compiler works by producing bytecode from the program source; this bytecode can be interpreted to execute the program
immediately; alternatively, a backend can produce something else from the bytecode, for example C or Perl source code which can then be
compiled to your computer's native object format.
The compiler itself is just some more bytecode. Thus, to produce the compiler you need a compiler compiler, and to produce that you need a
compiler compiler compiler; to produce the latter you would need a compiler compiler compiler compiler, and so on to infinity. To simplify
the programmer's life (eh?), the compiler compiler is able to compile itself, and is therefore identical to the compiler compiler compiler
(etcetera).
The programmer can start the process because a pre-compiled compiler compiler, in the form of bytecode, is provided with the CLC-INTERCAL
distribution; this compiler compiler then is able to compile all other compilers, as well as to rebuild itself if need be.
See the online manual or the HTML documentation included with the distribution for more information about this.
