$1\mathrm{.}36$ Write a user$-$defined PYTHON function that converts real numbers in decimal form to binary form.

Name the function $b=$ deciTObina $($d$),$ where the input argument $d$ is the number to be converted and

the output argument $b$ is a $30-$element$-$long vector with $1s$ and $0s$ that represents the number in binary

form. The first $15$ elements of $b$ store the digits to the left of the decimal point, and the last $15$ elements of

b store the digits to the right of the decimal point. If more than $15$ positions are required in the binary form

for the digits to the right of the decimal point, the digits should be chopped. If the number that is entered as

$d$ is larger than can be stored in $b,$ the function should display an error message. Use the deci TObina in

the Command Window to convert the numbers $85\mathrm{.}321,0\mathrm{.}00671,$ and $3006\mathrm{.}42.$ Some Python$/$R built in functions such as $$bin$()$ must not be used.
