Apparently MSVC has syntax for 32bit and 64bit integer literal suffix. It’s like: unsigned __int32 s = 0xffffffffui32; unsigned __int64 s2 = 0xffffffffffffffffui64; __int32 s3 = 0xffffffffi32; __int64 s4 = 0xffffffffffffffffi64; __int64 s5 = 12i64; __int32 s6 = 07i32; Encountered this as my copy of <stdint.h> defines SIZE_MAX using these suffixes. I can’t find where these suffixes are documented.

It's Microsoft specific: https://learn.microsoft.com/is-is/cpp/c-language/c-integer-constants?view=msvc-160 although there is no mention of i32.
