0.1 float is greater than 0.1 double. I expected it to be false [duplicate]
...id. This difference can and does actually occur, because x86 does not use 64-bits for its internal floating-point computations; it actually uses 80-bits! This is called double extended-precision.
So, even among just x86 compilers, it sometimes happen that the same number is represented two differ...

A fast method to round a double to a 32-bit int explained
...
For those who'd like to convert to int64_t you can do that by shifting the mantissa left and then right by 13 bits. This will clear the exponent and the two bits from the 'magic' number, but will keep and propagate the sign to the entire 64-bit signed integer. un...

What are the mechanics of short string optimization in libc++?
...chine, 10 chars will fit in the short string. sizeof(string) is 12.
On a 64 bit machine, 22 chars will fit in the short string. sizeof(string) is 24.
A major design goal was to minimize sizeof(string), while making the internal buffer as large as possible. The rationale is to speed move constru...
