Program to calculate tax inclusive or exclusive from giving price.

This program is similar to other 4 function calculator
That have [TAX-] and [TAX+] features.

Manual calculation is also fast and effective but this
Program help ease with less keystrokes to the results.
———————————————————————————-
Procedure: FIX 2

To Reset or Start Over: f. [PGRM] or [GTO] 00

Set Tax Rate Percent at Register 0 , [STO] 0

———————————————————————-
Initialize with 0 or 1

0 for exclusive tax [TAX-]
1 for inclusive tax [TAX+]
————————————————————————
Example: f [PRGM]

For tax of 8%

8 [STO] 0 // store 8% tax

$54 include tax, What is the original price without tax?$ 100 include tax, What is the original price without tax?

0 [R/S] display 0.00 // initialize for tax exclusive [TAX-]

54 [R/S] display -50.00 [X<>Y] 4.00

100 [R/S] display -92.59 [X<>Y] 7.41

$54 without tax is$50 and tax amount is $4$100 without tax is $92.59 and tax amount is$7.41

————————————————————————————-
Example: Inclusive Tax [TAX+]

f [PGRM]

1 [R/S] display 1 // initialize for tax inclusive [TAX+]

Use the same 8% tax from previous example

What is the price include tax of $45 What is the price include tax of$105

45 [R/S] display 48.60 [X<>Y] 3.60
105 [R/S] display 113.40 [X<>Y] 8.40
————————————————————————————
