Below is a program which converts a double to an integer in two
different ways, giving me two different values for the int. The basic
expression is 1.0 / (1.0 * 365.0) which should be 365, but one variable
becomes 364 and the other one becomes 365.
Does anyone have any insight to what the problem is?
Thanks in advance.

Could anyone please help me to understand what is happening here? The
commented line produces an error, which is what I expected given that
there is no conversion defined from type double to type Test. I
expected the same error from the following line, but it compiles fine.
The double is silently truncated to an int and then fed in to the...

I'm struggling with the string conversion to MD5 which I've never user
before.
I have a string that I need to encode which looks approximately like this:

Hi there,
Is there a way to convert a double value to a string. I know that there
is fcvt() but I think this function is not a part of the standard
library. I want sth from the standard if possible.
The thing I am trying to do is to convert a double value to a string
with 8 elements. 8 is fixed because of the files I work with. I will...

Would it be wrong to use "implicit casting" instead of the standards
"implicit conversion" when talking about implicit conversions between
certain data types. The standard mentions "explicit conversion" for a
cast operation

Hello,
I am somewhat lost in the implicit/expicit possible/impossible type casting
in C#...
I need to write a class, which among other things, must have wat to read a
numeric value type, and internally convert it so that it could be saved in
database as real number (float). I plan to provide property(set) interface
for reading the value.

I need a conversion function that converts values from string to a
particular type. For this I have a template function that looks like
this ...
template<class T>
T value(const string& s)

I am baffled by this behaviour.
I have a class A declared as follows:
class A

public:
A();
explicit A(const std::string& value);
explicit A(const TimestampParam& value) ;

hi
i need a fast way to do lots of conversion that between
string and numerical value(integer, float, double...), and
boost::lexical_cast is useless, because it runs for a long time,
(about 60 times slower than corresponding C functions)
it's too expensive for my program.
is there any way( library?) to do this fast and safely,
please ?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
