Floating-Point Parameters - MATLAB Code for Parameters of Floating-Point Arithmetics
About
float_params is a MATLAB function for obtaining the parameters of several
floating-point arithmetics. The parameters are built into the code and are
not computed at run time.
The parameters are
- the unit roundoff,
- the smallest positive (subnormal) floating-point number, xmins,
- the smallest positive normalized floating-point number, xmin,
- the largest floating-point number, xmax,
- the number of binary digits in the significand (including the implicit leading bit),
- the exponent of xmins,
- the exponent of xmin,
- the exponent of xmax
and the arithmetics supported are
- NVIDIA quarter precision (fp8-e4m3, fp8-e5m2),
- bfloat16,
- IEEE half precision (fp16),
- NVIDIA tf32,
- IEEE single precision (fp32),
- IEEE double precision (fp64),
- IEEE quadruple precision (fp128).
The code was developed in MATLAB R2020a and works with versions at least back to R2016b.
