Wrong idiots unsigned should only be used when doing bit twiddling, not arithmetic.

pythons got some weird rear end typecasting

code:

s8 = (i + 2**7) % 2**8 - 2**7      // convert to signed 8-bit
u8 = i % 2**8                      // convert to unsigned 8-bit
s16 = (i + 2**15) % 2**16 - 2**15  // convert to signed 16-bit
u16 = i % 2**16                    // convert to unsigned 16-bit
s32 = (i + 2**31) % 2**32 - 2**31  // convert to signed 32-bit
u32 = i % 2**32                    // convert to unsigned 32-bit
s64 = (i + 2**63) % 2**64 - 2**63  // convert to signed 64-bit
u64 = i % 2**64                    // convert to unsigned 64-bit

i do like how ints and longs are one and the same tho

wtf are you doing numpy or what? because smdh if you're thinking about specific integer types in vanilla python

and yeah, this was a good change from python2 to python3 (ints and longs being the same)

I can kinda see why it's that way though, like if you made a list of the primitive types all the other forms without modifiers are signed

The weirdest thing I can see is that char, signed char, and unsigned char are considered different and distinct types

BigNumber.js

code:

var girl, cum, ears, my
cum = BigNumber(420)
my = 69
ears = 2

girl = cum.minus(my).minus(ears).div(2).toPrecision(17)
girl = parseInt(girl, 10)

then you accidentally compare against a signed int (because everyone uses signed for everything, because it's the default) and life is suffering

I saw the sign

as a function return value to determine error state

if you aren't checking your compiler warnings to see if you are comparing signed and unsigned then you deserve your many hours of debugging your bad code

same if you don't check your function returns anyway

I guess you can use exceptions if you write C++ but keep that hot mess away from me
