Functions

==[anchor|#Functions_and_Regional_Settings]Functions and Regional Settings==

It is important to note that SMath has a very good '''Multilanguage''' and '''Regional Setting''' support. Therefore, the user should take care about the Regional settings. 

NOTE: See the argument and decimal separator character in the '''Arithmetic''' palette.

Here is the example of the Regional Settings when '''comma''' is the '''function argument separator''' and '''point''' is the '''decimal separator'''

'''These settings are mainly used in the English part of the wiki'''.

For many European languages, the SMath could be used with '''semicolon''' as the '''function argument separator''' and '''comma''' as the '''decimal separator'''

NOTE: There is also a possibility to change the function argument and decimal separators without leaving SMath. You can change it from '''Tools=>Options=>Interface''' dialog box. There are '''Decimal symbol''' and '''Arguments separator''' options.

==[anchor|#Built-in_Functions]Built-in Functions==

The names of the built in functions depend on the menu option '''Tools=>Options''' and the '''Interface''' tab. There are two options under '''Functions style''' : '''World''' and '''Europe'''. For instance, function for the inverse cosine is '''acos''' in the '''World style''' and '''arccos''' in the '''Europe style''':

[imageauto|Europe|{UP}userfunchints/europe.png]

NOTE: The saved files will be opened and the function names will be used according to the chosen style. It is not possible to change the style in the active file - the error (unknown function) will occur.

These are some of the '''[[built in functions]]''' for SmathStudio.

*[[augment]]
*[[cofactor]] (alg)
*[[diff]]
*[[eval]]
*[[findrows]]
*[[int]]
*[[linterp]]
*[[minor]]
*[[mod]]
*[[numden]]
*[[polyroots]]
*[[roots]]
*[[round]]
*[[solve]]
*[[sorting]]
*[[splines]]
*[[stack]]
*[[vminor]]

These functions are not built in but you might need to use them

*[[ceil]]
*[[floor]]
