Literal suffix for byte in .NET?
... SB is two-fold.
One, the B suffix is ambiguous if you're writing in hexadecimal (what
does 0xFFB mean?) and even if we had a solution for that, or another
character than 'B' ('Y' was considered, F# uses this) no one could
remember whether the default was signed or unsigned - .NET bytes ...
How to parse a string to an int in C++?
...her bases by setting the stream to the correct mode (e.g. ss << std::hex) before trying the conversion. But this means the caller must know a priori what base the number is -- and how can the caller possibly know that? The caller doesn't know what the number is yet. They don't even know that i...

What's the difference between ASCII and Unicode?
...II tables show character codes as 0-127 but UTF-8 tables show the codes as hex and not integers. Is there a reason for this? Why don't UTF-X tables show 0-127/255/65535 versus 00-AF? Does this mean anything?

Control the size of points in an R scatterplot?

Sprintf equivalent in Java

For instance, to convert a value to a hex string, you have the 2 following solutions:

String ret;

parseInt vs unary plus, when to use which?
...t of @Alex K., parseInt and parseFloat will parse by character. This means hex and exponent notations will fail since the x and e are treated as non-numerical components (at least on base10).
The unary + will convert them properly though.
parseInt('2e3',10) === 2; //true. This is supposed to be 2...
