Primitive Data Types: reference to IEEE floating-point standard in integers section

I'm confused

  • In section "i8, i16, i32, i64, i128":

    Min and max values are based on IEEE standard for Binary Floating-Point Arithmetic.

  • In section "u8, u16, u32, u64, u128":

    Same as signed numbers, min and max values are based on IEEE standard for Binary Floating-Point Arithmetic.

Does "IEEE standard for Binary Floating-Point Arithmetic" means IEEE 754? I think it doesn't specify integer numbers. It even says in section "2. Definitions, abbreviations, and acronyms ":

2.1.32 integer format: A format not defined in this standard that represents a subset of the integers and perhaps additional values representing infinities, NaNs, or negative zeros.

Hi @demin-dmitriy,
Thanks for reporting this. Looks like I misunderstood this in my early days of Rust, https://www.reddit.com/r/rust/comments/3p1vgg/ranges_for_integer_data_types/ .
Will update in this weekend :)

PS. Sorry, Will update within this month.
