; Help for complex numbers
symcomplex
Expressions with complex numbers are written using an i to denote#NEWLINE#the imaginary value. Complex numbers can seamlessly be mixed with#NEWLINE#real numbers.#NEWLINE##SYNTAXHIGHLIGHT#Syntax:  2+3i#NEWLINE#Example: 2+3.2i*cos(-1i)+5/7#NEWLINE#
; Help for clear statement
symclear
The clear statement erases all text in the console window.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: clear#NEWLINE#
; Help for def statement
symdef
The def statement is used to define functions. When defining a function#NEWLINE#it is possible to omit the def keyword. Defined functions can be shown#NEWLINE#using the functions statement.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: def f(x)=2*x+3#NEWLINE#Optional syntax: f(x)=2*x+3#NEWLINE#
; Help for delete statement
symdelete
The delete statement can delete variable and functions. To delete a#NEWLINE#single variable or functions use the name of the function or variable.#NEWLINE#To delete all functions or variables specify either the variable or#NEWLINE#function keyword.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: delete f(x)#NEWLINE#Syntax: delete variables#NEWLINE#
; Help for digits statement
symdigits
The digits statement defines the displayed number of significant digits.#NEWLINE#To show current configuration use the digits statement without specifying#NEWLINE#the number.#NEWLINE# #SYNTAXHIGHLIGHT#Syntax: digits 7#NEWLINE#
; Help for eval statement
symeval
The eval statement evaluates an expression. When evaluating an expression#NEWLINE#it is possible to omit the eval keyword.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: eval 2.4*x+3.2#NEWLINE#Optional syntax: 2.4*x+3.2#NEWLINE#
; Help for execute statement
symexecute
The execute statement reads the content of a file and execute all statements.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: execute "savedfile"#NEWLINE#
; Help for input statement
syminput
The input statement either changes or shows the how numeral input is interpreted.#NEWLINE#Possible input systems are: binary, octal, decimal and hexadecimal. Default is#NEWLINE#decimal. To use positional systems with other bases specify the base number.#NEWLINE#Numeral output system can be modified using the output statement.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: input hexadecimal#NEWLINE#Syntax: input 4#NEWLINE#
; Help for help statement
symhelp
The help statement can be used to display help about topics and statements.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: help variables#NEWLINE#
; Help for output statement
symoutput
The output statement either changes or shows the how numeral output is shown.#NEWLINE#Possible output systems are: binary, octal, decimal and hexadecimal. Default#NEWLINE#is decimal. To use positional systems with other bases specify the base number.#NEWLINE#Numeral input system can be modified using the input statement.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: output octal#NEWLINE#
; Help for list statement
symlist
No description is available for the list statement.#NEWLINE#
; Help for show statement
symshow
The show statement displays the content of a file.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: show "filetosee"#NEWLINE#
; Help for load statement
symload
The load statement retrieves a set of defined variables and functions from#NEWLINE#a file. Variables and functions can be saved using the save statement.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: load "savedwork"#NEWLINE#
; Help for save statement
symsave
The save statement saves defined variables and functions to a file in a#NEWLINE#plain text format. Saved variables and functions can be retrieved using#NEWLINE#the load statement.#NEWLINE# #SYNTAXHIGHLIGHT#Syntax: save "worktokeep"#NEWLINE#
; Help for version statement
symversion
Show which version of amath is running.#NEWLINE#
; Help for memory statement
symmem
Show internal memory usage together with maximum usage.#NEWLINE#
; Help for prefs statement
symprefs
There is no help for prefs statement now.#NEWLINE#
; Help for variable statement
symvariable
The variable statement shows a list of variables in memory.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: variables#NEWLINE##NORMALTEXT#optional syntax: vars#NEWLINE#
; Help for exit statement
symexit
The exit statement shuts down amath.#NEWLINE##SYNTAXHIGHLIGHT#Syntax: exit#NEWLINE#
; Help for constant epsilon
syme
Euler's number is base of the exponential function which equals its own#NEWLINE#derivative. It is approximately equal to 2.71828.#NEWLINE##SYNTAXHIGHLIGHT#Example: ln(e)#NEWLINE#
; Help for constant pi
sympi
Pi is the ratio of the circumference of a circle to its diameter. Being an#NEWLINE#irrational number, pi cannot be expressed exactly as a common fraction.#NEWLINE#The value of pi is commonly approximated as #SYNTAXHIGHLIGHT#3.14159#NORMALTEXT#.#NEWLINE#
; Help for imaginary unit
symi
The imaginary unit is denoted and commonly referred to as i.#NEWLINE#The imaginary unit is a number, which when multiplied#NEWLINE#by itself gives -1.#NEWLINE#
