I want to convert this value to floating point value in PERL scripting.
I tried googling for the solution, and also asked many perl friends. Unfortunately, I didn't get answer.
Could you please help me?
Thanks in advance / Mysore Ganapati.

Does anyone have a simple way of doing floating point ("fp") division? For example, if I divide 3 by 5, I can get 0.6. The built-in calc (`bc`) will perform fp multiplication, but not division, at least not straight-up (i.e., starting bc and just typing in 3/5).

hi, :)
I have a file like this

Hi,
I am compiling "HelloWorld" C progam on 32-bit CentOS and i want to execute it on 64-bit CentOS architecture.
For that i copied the a.out file from 32-bit to 64-bit machine, but while executing a.out file on 64bit machine I am getting "Floating point exception error".

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,

floating_to_decimal
floating_to_decimal(3C)floating_to_decimal(3C)NAME
floating_to_decimal, single_to_decimal, double_to_decimal, extended_to_decimal, quadruple_to_decimal - convert floating-point value to dec-
imal record
SYNOPSIS
#include <floatingpoint.h>
void single_to_decimal(single *px, decimal_mode *pm, decimal_record *pd, fp_exception_field_type *ps);
void double_to_decimal(double *px, decimal_mode *pm, decimal_record *pd, fp_exception_field_type *ps);
void extended_to_decimal(extended *px, decimal_mode *pm, decimal_record *pd, fp_exception_field_type *ps);
void quadruple_to_decimal(quadruple *px, decimal_mode *pm, decimal_record *pd, fp_exception_field_type *ps);
The floating_to_decimal functions convert the floating-point value at *px into a decimal record at *pd, observing the modes specified in
*pm and setting exceptions in *ps. If there are no IEEE exceptions, *ps will be zero.
If *px is zero, infinity, or NaN, then only pd->sign and pd->fpclass are set. Otherwise pd->exponent and pd->ds are also set so that
(sig)*(pd->ds)*10**(pd->exponent)
is a correctly rounded approximation to *px, where sig is +1 or -1, depending upon whether pd->sign is 0 or -1. pd->ds has at least one
and no more than DECIMAL_STRING_LENGTH-1 significant digits because one character is used to terminate the string with a null.
pd->ds is correctly rounded according to the IEEE rounding modes in pm->rd. *ps has fp_inexact set if the result was inexact, and has
fp_overflow set if the string result does not fit in pd->ds because of the limitation DECIMAL_STRING_LENGTH.
If pm->df == floating_form, then pd->ds always contains pm->ndigits significant digits. Thus if *px == 12.34 and pm->ndigits == 8, then
pd->ds will contain 12340000 and pd->exponent will contain -6.
If pm->df == fixed_form and pm->ndigits >= 0, then the decimal value is rounded at pm->ndigits digits to the right of the decimal point.
For example, if *px == 12.34 and pm->ndigits == 1, then pd->ds will contain 123 and pd->exponent will be set to -1.
If pm->df == fixed_form and pm->ndigits< 0, then the decimal value is rounded at -pm->ndigits digits to the left of the decimal point, and
pd->ds is padded with trailing zeros up to the decimal point. For example, if *px == 12.34 and pm->n digits == -1, then pd->ds will contain
10 and pd->exponent will be set to 0.
When pm->df == fixed_form and the value to be converted is large enough that the resulting string would contain more than DECI-
MAL_STRING_LENGTH-1 digits, then the string placed in pd->ds is limited to exactly DECIMAL_STRING_LENGTH-1 digits (by moving the place at
which the value is rounded further left if need be), pd->exponent is adjusted accordingly and the overflow flag is set in *ps.
pd->more is not used.
The econvert(3C), fconvert(3C), gconvert(3C), printf(3C), and sprintf(3C) functions all use double_to_decimal().
