=========
Display/show/analyze IEEE754 Half-precision, Single-precision, and Double-precision values; along with various
integer types: Signed/Unsigned, 8, 16, 32, 64 bits.
$ crackNum --help
crackNum v1.1, (c) Levent Erkok. Released with a BSD3 license.
Usage: crackNum precision bit/hex-pattern
--hp 16 bit half precision
--sp 32 bit single precision
--dp 64 bit double precision
--sb 8 bit signed byte
--sw 16 bit signed word
--sd 32 bit signed double
--sq 64 bit signed quad
--ub 8 bit unsigned byte
--uw 16 bit unsigned word
--ud 32 bit unsigned double
--uq 64 bit unsigned quad
--toIEEE=n Convert from decimal to IEEE SP/DP formats.
-l n --lanes=n number of lanes
-h, -? --help print help, with examples
-v --version print version info
Examples:
crackNum --hp fc00
crackNum --sp fc00 abcd
crackNum --dp fc00 abc1 2345 6789
crackNum --sp 01111111110000000000000000000000
crackNum -l2 --hp 01111111110000000000000000000000
crackNum --sb 7f
crackNum --sp --toIEEE=-2.3e6
crackNum --dp --toIEEE=max
crackNum --dp --toIEEE=ulp
Notes:
- You can use hexadecimal or binary as input.
- You can use _,- or space as a digit to improve readability.
- You can give input for multiple lanes, we will guess the #of lanes for you.
Or, you can specify number of lanes with the -l option.
- For "toIEEE" option:
- You can enter a number in decimal notation (like 2.3)
- OR, enter one of the following:
* infinity, -infinity: Positive/Negative infinities
* snan, qnan: Not-A-Number; screaming/quiet
* 0, -0: Both kinds of zeros
* max : The maximum finite positive value
* -max: The minimum finite negative value
* min : The minimum normal positive value
* -min: The maximum normal negative value
* epsilon: The smallest possible value x s.t. 1+x /= 1.
* ulp: The minimum subnormal value
