Multiplication with Fractions
Hello there,
how do i multiply a fraction and a whole number? Example 20% of 50,000.
I had gotten 0.2 using the following:
chk=echo 20 100 | awk `{print $1/$2}`
echo $chk
$chk \* 50000 displays the error: non-numeric expression.

encode::gsm0338
Encode::GSM0338(3pm) Perl Programmers Reference Guide Encode::GSM0338(3pm)
NAME
Encode::GSM0338 -- ESTI GSM 03.38 Encoding
SYNOPSIS
use Encode qw/encode decode/;
$gsm0338 = encode("gsm0338", $utf8); # loads Encode::GSM0338 implicitly
$utf8 = decode("gsm0338", $gsm0338); # ditto
DESCRIPTION
GSM0338 is for GSM handsets. Though it shares alphanumerals with ASCII, control character ranges and other parts are mapped very
differently, mainly to store Greek characters. There are also escape sequences (starting with 0x1B) to cover e.g. the Euro sign.
This was once handled by Encode::Bytes but because of all those unusual specifications, Encode 2.20 has relocated the support to this
module.
NOTES
Unlike most other encodings, the following aways croaks on error for any $chk that evaluates to true.
$gsm0338 = encode("gsm0338", $utf8 $chk);
$utf8 = decode("gsm0338", $gsm0338, $chk);
So if you want to check the validity of the encoding, surround the expression with "eval {}" block as follows;
eval {
$utf8 = decode("gsm0338", $gsm0338, $chk);
};
if ($@){
# handle exception here
}
BUGS
ESTI GSM 03.38 Encoding itself.
Mapping x00 to '@' causes too much pain everywhere.
Its use of x1b (escape) is also very questionable.
Because of those two, the code paging approach used use in ucm-based Encoding SOMETIMES fails so this module was written.
