|

// 1. GNU seq uses long double (80-bit) types for values, while the current implementation
|

// relies on f64 (64-bit). This can lead to differences due to varying precision. However, it's
|
||
// likely not the primary cause, as even double (64-bit) values can differ when compared to
|
||
// f64.
|

//
|

// 2. GNU seq uses the %Lg format specifier for printing (see the "get_default_format" function
|
||
// ). It appears that Rust lacks a direct equivalent for this format. Additionally, %Lg
|
||
// can use %f (floating) or %e (scientific) depending on the precision. There also seem to be
|
||
// some differences in the behavior of C and Rust when displaying floating-point or scientific
|
||
// notation, at least without additional configuration.
|

//
|

// It makes sense to begin by experimenting with formats and attempting to replicate

// the printf("%Lg",...) behavior. Another area worth investigating is glibc, as reviewing its

// code may help uncover additional corner cases or test data that could reveal more issues.
