# Common Functions

 x\$+y\$ String concatenation. Chr\$(x) Returns the ASCII character corresponding to the value (x) Str\$(x) Returns a string representation of the value of (x). The number of decimal places can be set by the FixDecimal command. Left\$(x\$,y) Returns the left (y) characters of x\$. Right\$(x\$,y) Returns the right (y) characters of x\$ Replace\$(x\$,y\$,z\$) Returns a string (x\$) with all occurrences of (y\$) replaced with (z\$). String\$(x\$,y) Returns a string containing (x\$) replicated (y) times. Upper\$(x\$) Returns a string containing (x\$) in upper case. Lower\$(x\$) Returns a string containing (x\$) in lower case. Trim\$(x\$) Returns a string containing (x\$) with the white space removed from the beginning and end. TrimLeft\$(x\$) Returns a string containing (x\$) with the white space removed from the beginning of the string. TrimRight\$(x\$) Returns a string containing (x\$) with the white space removed from the end of the string.

# Numeric String Functions

 isNumber(n\$) This function returns true (1) if the string parameter is a valid numeric expression, if not false (0) is returned. Parse\$(e\$) This function parses a valid numeric expression and returns the result as a numeric text string. If an error occurs "Error" is returned. SciNot\$(x) Returns a string containing the value of (x) in scientific notation. Bin\$(x) Returns a string containing the value of (x) in binary. Oct\$(x) Returns a string containing the value of (x) in octal. Hex\$(x) Returns a string containing the value of (x) in hex. BinDec(x\$) Returns the decimal value of a string (x\$) containing a binary value. OctDec(x\$) Returns the decimal value of a string (x\$) containing an octal value. HexDec(x\$) Returns the decimal value of a string (x\$) containing a hex value. Len(x\$) Length of a string (x\$) ASCII(x\$) ASCII value of (x\$) Val(x\$) Numeric value of (x\$) ValLen(x) Length of (x) as a string. The number of decimal places can be adjusted with the FixDecimal command. InStr(x\$,y\$,z) Returns the index to the first occurrence of the substring (y\$) in the string (x\$). Searching begins at the offset (z). If the substring is not found then 0 is returned. DeviceID\$() Returns a string that is a unique device (phone) ID. AndroidVersion\$() Returns the Android version running on the device. BasicVersion\$() Returns the currently running Basic version number.
