Crate hexf_parse[−][src]
Parses hexadecimal float literals.
There are two functions parse_hexf32
and parse_hexf64
provided for each type.
use hexf_parse::*; assert_eq!(parse_hexf32("0x1.99999ap-4", false), Ok(0.1f32)); assert_eq!(parse_hexf64("0x1.999999999999ap-4", false), Ok(0.1f64));
An additional bool
parameter can be set to true if you want to allow underscores.
use hexf_parse::*; assert!(parse_hexf64("0x0.1_7p8", false).is_err()); assert_eq!(parse_hexf64("0x0.1_7p8", true), Ok(23.0f64));
The error is reported via an opaque ParseHexfError
type.
