bash only supports integer arithmetic, it does not support floating point arithmetic. You have to use a external utility such as bc to do floating point arithmetic.

NAME
ilogb(), ilogbf(), ilogbl(), ilogbw(), ilogbq() - radix-independent exponent functions
SYNOPSIS
Integrity Server Only
DESCRIPTION
The function computes the exponent of the floating point value x. Formally, the return value is the integral part of log base r of |x| as
a signed integral value, for nonzero x, where r is the radix of the machine's floating-point arithmetic. The radix r is 2 on HP-UX sys-
tems.
If x is denormal it is treated as though it were normalized before the exponent is determined.
Note: is equivalent to for all values of x
Integrity Servers Only

USAGE
To use these functions, compile either with the default option or with the and options.
To use (for Integrity servers) or compile also with the option.
Make sure your program includes Link in the math library by specifying on the compiler or linker command line.
For more information, see the at the following site:
RETURN VALUE
If x is NaN, returns
If x returns
If x is zero, returns

If x is NaN, +-INFINITY, or zero, then the invalid floating-point exception is raised (as specified by C99 TC2)
