Modules

error 🔒

Error types for conversion to integral types.

int_log10 🔒

These functions compute the integer logarithm of their type, assuming that someone has already checked that the value is strictly positive.

int_macros 🔒

int_sqrt 🔒

These functions use the Karatsuba square root algorithm to compute the integer square root for the primitive integer types.

libm 🔒

Bindings to math functions provided by the system libm or by the libm crate, exposed via compiler-builtins.

nonzero 🔒

Definitions of integer that is known not to equal zero.

overflow_panic 🔒

Functions for panicking on overflow.

saturating 🔒

Definitions of Saturating<T>.

uint_macros 🔒

wrapping 🔒

Definitions of Wrapping<T>.

bignum 👻 Experimental

Custom arbitrary-precision number (bignum) implementation.

dec2flt 👻 Experimental

Converting decimal strings into IEEE 754 binary floating point numbers.

diy_float 👻 Experimental

Extended precision “soft float”, for internal use only.

flt2dec 👻 Experimental

Floating-point number to decimal conversion routines.

fmt 👻 Experimental

Shared utilities used by both float and integer formatting.

niche_types 👻 Experimental

100% perma-unstable

Macros

from_str_int_impl 🔒

i8_xe_bytes_doc 🔒

midpoint_impl 🔒

sign_dependent_expr 🔒

try_opt 🔒

u8_xe_bytes_doc 🔒

usize_isize_from_xe_bytes_doc 🔒

usize_isize_to_xe_bytes_doc 🔒

Enums

FpCategory

A classification of floating point numbers.

Constants

ASCII_CASE_MASK 🔒

If the bit selected by this mask is set, ascii is lower case.

Functions

from_ascii_radix_panic 🔒

can_not_overflow 👻 Experimental

Determines if a string of text of that length of that radix could be guaranteed to be stored in the given type T. Note that if the radix is known to the compiler, it is just the check of digits.len that is done at runtime.
