FMT Menu
This menu is used to format numbers.
You can access the FMT Menu pressing
[CST] |FMT|


1) STD
Set number format to standard.
Standard format has 12 digits.
The zeroes after last non-zero digit are not displayed.

Keyboad Access:
[CST] |FMT| |STD|


Example:

3


Result: 1.73205080757 		Example:

5.0625


Result: 2.25


2) FIX
Fix the number format to a pre-definite number, rounding it.

Keyboad Access:
[CST] |FMT| |FIX|

Example:

3

Result:1.7320508757

Fixing format to 4
[CST] |FMT| |FIX|  [ 4 ]

Result:1.7321


3) SCI
Set the number format to scientific mode.
Keyboad Access:
[CST] |FMT| |SCI|

Example:

123456789
3
[CST] |FMT| |SCI|

Result: 1.23E8


4) ENG
Set the number format to Engeneering mode.
It is similar to SCI, but the exponent is a multiple of 3.

Keyboad Access:
[CST] |FMT| |ENG|

Example 1:

123456789
3
[CST] |FMT| |ENG|

Result: 123.5E6 		Example 2:

.0000056
5
[CST] |FMT| |ENG|

Result:5.600E-6 		Example 3:

1200
7
[CST] |FMT| |ENG|

Result: 1.20000000E3



5) FM
Set the fraction mark to comma "," or dot ".".


6) ML
Show result without break line if clear or
with line breaked if set.

Keyboad Access: [CST] |FMT| |ML|

Example:

(-2,-5)

[CST] |FMT| |ML|

Case 1:
1-If it is set: [ML.] (dot appears)
Result:
(1.300992853,
 -1,92160932647) 		Case 2:
2-If it is clear: [ML](dot does not appear)
Result:
(1.300992853,-1,92...)
(last numbers are trucated.)



Trigonometric Functions
Trigonometric functions work with RAD,DEG or GRAD angle mode.

1) SIN(X)
Returns the sine of an angle

Example:
25 (DEG mode set)
[SIN]

Result: .422618261741


2) COS(X)
Returns the cosine of an angle

Example:
25 (DEG mode set)
[COS]

Result: 3.73205080757


3) TAN(X)
Returns the tangent of an angle
Example:

75 (DEG mode set)
[TAN]

Result: 3.73205080757


4) ASIN(X)
Returns the arc sine of an angle

Example:
.3 (RAD mode set)
[ASIN]

Result: .304692654015


5) ACOS(X)
Returns the arc cosine of an angle

Example:
.3 (RAD mode set)
[ACOS]
Result: 1.26610367278


6) ATAN(X)
Returns the arc tangent of an angle.

Example:
.87 (RAD mode set)
[ATAN]

Result: .7115991114416



Log Functions
1) LOG
Calculates the decimal logarithim of a number.

Example:
8
[LOG]

Result:.903089986992


2) LN
Calculates the natural (Neppier) logarithm of a number.

Example:
8
[LN]

Result:2.07944154168


3) ex
Returns e to the X power

Example:
5
 ex

Result: 148.413159103


4) 10x
Returns the antilog of a number.

Example:
5
10x

Result:100000



Inverse, Root and Xroot Functions
1) 1/X
Returns the inverse of a number

Example:

55
1/X


Result:.181818181818E-2


2) 
Returns the square root of a number.

It is the same that 'XROOT(2,Y)' where Y is a number.

Example:
7


Result: 2.64575131106


3)
Returns the root X of a number Y
It is the same that 'XROOT(X,Y)',
where X is the root exponent and Y the radicand.

Example 1:
12 (value for Y)
3 (value for X)


Result: 2.28942848511 		           Example 2:
'XROOT(3,12)'
[EVAL]

Result: 2.28942848511



4) XY

Example:
5
3
XY

Result:125
( that indeed is equal 53)
