>Description:
awk supports decimal floating-point input, and hexadecimal floating-point output:
% awk 'BEGIN { OFMT = "%a"; print 1.1102230246251565e-16 }'
0x1p-53
But the hexadecimal notation doesn't work on input:
% awk 'BEGIN { print 0x1p-53 }'
0-53
The hexadecimal floating-point notation is a much clearer way to write many floating-point constants without the deception of decimal approximations.
>How-To-Repeat:
Try to enter hexadecimal floating-point input.
>Fix:
Yes please!
