You are correct - you need awk, perl, bc, etc. to do floating point arithmetic.
Not shell - shell does not support FP.

how to compare 2 floating point no.

Hi, Could any one tell me how to compare to floating point no. using test command. As -eq option works on only intergers. i=5.4 if then echo "equal" else echo "not equal" fi here output will be equal even though no. are unequal. Thanks, ravi (1 Reply)

NAME
nextafterd64(), nextafterd128(), nextafterd32(), nexttowardd64(), nexttowardd128(), nexttowardd32() - next representable decimal floating- point numbers SYNOPSIS
DESCRIPTION
The function computes the next representable number following x in the direction toward y. Thus, if y is less than x, returns the largest representable number less than x. The function returns y if x equals y. The function is equivalent to except that the second parameter has the widest decimal floating-point type, and the function returns y con- verted to the type of the function if x equals y. The result of the function is determined in the type of the function, without loss of range or precision in a floating second argument, whose type may be wider than the type of the function. is a version of it takes arguments and returns a result. is a version of it takes arguments and returns a result. is a version of it takes a first argument and returns a result. is a version of it takes a first argument and returns a result. These math functions are supported for HP-UX 11i Version 3 September 2008 Update and forward. USAGE
To use any of these functions, compile with the option. Make sure your program defines and then includes Link in the math library by specifying or on the linking command line. For more information, see the at the following site: RETURN VALUE
If x equals y, returns y, and returns y converted to the type of x. If x is finite and the correct function value would overflow, these functions return according to the sign of x, and raise the overflow and inexact floating-point exceptions. If the return value is subnormal and x!=y, these functions raise the underflow and inexact floating-point exceptions. If x or y is NaN, these functions return NaN. ERRORS
If x is finite and the correct function value would overflow, these functions set to SEE ALSO
scalbnd64(3M), math(5). STANDARDS CONFORMANCE
These functions conform to ISO/IEC TR 24732, "Extension for the programming language C to support decimal floating-point arithmetic". HP Integrity Server Only nextafterd64(3M)
