function input easy

dntk can use function.

you can use under function.

function	command	detail
(x)	(	Simple round bracket
sin(x)	s	Sin of trigonometric function
cos(x)	c	Cosin of trigonometric function
atan(x)	a	Tangent of inverse trigonometric function
log(x)	l	Logarithm function
exp(x)	e	Exponential function
j(n,x)	j	The n-order Bessel function

example, if you want to write (123 + 2) * 3, you type,

(
1
2
3
+
2
Enter
*
3
Enter

if you want to write a(123), you type,

a
1
2
3
Enter
*
c
6
7
8
*
1
2
3
Enter
Enter

very easy 😘

set fixed value

example, excange calculate AWS Billing, JPY -> USD, put fixed statement

set alias

you can use alias

$ dntk -a '<alias char>=<value>,<alias char>=<value>,...'

☝️ type,

x
*
y
*
y

you can write long long value very easy 😁

clean buffer

if you want to clean buffer, very easy, type r

Pipe use...

$ echo "123 * 2" | dntk | xargs echo
246

behave, like bc ☺️

Have a nice go hacking days✨😉
