AutoCalc Functions come in two flavours:

•General Convertor
Add this at the front of the equation and everything after it gets converted.  General Converters always go at the front of the equation and have a $ before them.

•Select Convertor
Add this before each number in the equation to work on just that number.

 

•Round Fraction

•Decimal to Hex

•Decimal to Binary

•Hex to Decimal

•Binary to Decimal

•Character to Ascii Code

•Character to Unicode Code

•Ascii Code to Character

•Unicode Code to Character

 

 

Round Fraction

$rf        Regular Mode

$rfs        Special Mode

Rounds fraction to the nearest division.

Say you have your fraction 2/3, but you need it in the closest possible eighths, so to round 2/3 to the nearest eighth, you type:

$rf 2/3,8

 

Now, there are two modes for this function; both will provide the closest possible value and will round up or down to get your closest fraction.

•$rf mode

owill try to preserve the denominator you chose and will not simplify the fraction

 

•$rfs mode

oprovides a more accurate answer, but does not try to preserve the denominator

owill simpifly the fraction if possible  (in other words, $rf 1/2,8 = 1/2 because it simplifies 4/8).

 

$rf 2/3,8 = 5/8

$rfs 2/3,8 = 431/647

 

$rf 1/2,4 = 2/4

$rfs 1/2,4 = 1/2

 

Here $rf gives us 2/3 because the denominator provided is 3 and it tries to give the closest value in that division

However, $rfs is more accurate because it doesn't have to match the denominator.

Remember that we are trying to round a fraction to the nearest fraction.  Here we are rounding to 3; if you wanted a fraction that was exactly 1/2 ÷ 3 you wouldn't use the Round Fraction function - you would simply calculate (1/2)/3 = 0.2  and use the Convert Answer to Fraction function to get 13/64.

$rf 1/2,3 = 2/3                

$rfs 1/2,3 = 1/2

 

 

 

Decimal to Hex

$h

A General Convertor

$h 10 = A

$h 11+1 = C

 

Decimal to Binary

$b

A General Convertor

$b 2+2 = 100

 

Binary to Decimal

A Select Convertor

Use ' for unsigned binary and two ' for a signed binary number.

'011 = 3

'11 = -1 (unsigned binary with one ' )

''11 = -1 (signed binary with two ' )

'100+'100 = 8

 

Hex to Decimal

A Select Convertor: 0x

(There isn't a General Convertor for this yet)

Just type 0x in front of any number to make it a hex value (rendered as decimal in the answer). You can mix this into your regular equation alongside decimal values.

0x10 + 0x11 = 33

10+0xA+1 = 21

 

Character to Ascii Code

$c

Converts a character into it's ascii code point.

It ignores the space key, however.  But in case you need to know that, space is 32.

$c 4 = 52

$c # = 35

 

Ascii to Character

$a

Converts an ascii code into it's character

$a 32 = [space] (even tells you if the character is a space character! If it just put a space you wouldn't see it)

$a 35 = #

$a 52 = 4

 

Unicode to Character

$u

Converts a unicode code into it's character.

$u 23 = #

$u 34 = 4

$u 0023 = #

$u 0x0023 = #

 

Character to Unicode

$n

Converts a character into it's unicode code point.  It won't fetch the space character though.  But in case you need it, it is 0x20.

$n # = 00x23

$n 4 = 00x34
