Suffixes for integer types


Suffixes for integer types

To fix this issue Why do we use suffixes for integer types? Can suffixes determine the integer type? ,
Why do we use suffixes for integer types?
code :
// Assume `long` is 32-bit
long long x = 12345678912345L; // Constant is LL due to range.
long long y = 1000LL * 1000 * 1000 * 1000; // y gets the expected value
long long z = 1000L * 1000 * 1000 * 1000; // UB due to long overflow.

reshape wide to long with character suffixes instead of numeric suffixes

it fixes the issue Inspired by a comment from @gsk3 on a question about reshaping data, I started doing a little bit of experimentation with reshaping data where the variable names have character suffixes instead of numeric suffixes. , This works (to specify to varying what columns go with who):
code :
reshape(dadmom, direction="long",  varying=list(c(2, 4), c(3, 5)), 
        sep="", v.names=c("name", "inc"), timevar="dadmom",
        times=c("d", "m"))

will be helpful for those in need Assuming all prefixes are at the end you can do the following using a dictionary of values.
code :
sizes_dict = {'B': 1, 'K': 1000, 'M': 1000000}

data = '12M'

for k, v in sizes_dict.items():
    if data[-1] == k:
        no_letters = int(data[:-1]) * v

print(no_letters)

it fixes the issue No, you are not wrong. The suffixes that hardcode "abstract" types like unsigned long are not very compatible with using the more concrete types with specified widths.
Sometimes people simply know the mapping, which can make it correct anyway, but it's not as portable or clean.

To fix this issue To which degree does the preprocessor regard integer literal suffixes? Or does it just ignore them?
The type suffixes of integer constants are not inherently meaningful to the preprocessor, but they are an inherent part of the corresponding preprocessing tokens, not separate. The standard has this to say about them:
What are the rules for 'typing' of parameters when explicit integer suffixes are not given?
