BoardSurfers: Data Type Conversion in Allegro SKILL Programming

float()

Example: 
X = float(34)

Result:

X = 34.0

int()

Example:
X = 2.9
Xint = int(X)

Result:

X = 2

Caution: Potential truncation issues with this operation.

atoi() converts string to integer 

Example:

X = atoi("10")

Result:

X = 10

atof() converts string to float

Example:

Y = atof("1.2e-12")

Result:

Y = 1.2e-12

Numeric Strings to Numbers

evalstring() numeric strings to numbers (integers or floats)

Example:

• evalstring("10")
  Result: 10
• evalstring("10.0")
  Result: 10.0
• evalstring("1+2")
  Result: 3

NOTE: You must cautiously use the evalstring() function to convert numeric strings. Any error in providing data type to this function may lead to incorrect results.
For example: evalstring("10/2.") => 5.0

Integer to String

sprintf()with %d format directive

Example:

sprintf(str, " %d ", 2)

Result: "2"

sprint() converts integer 2 to a string "2" (in double quotes) and stores it in the variable str.

Float to String

sprintf() with %g format directive

Example:

sprintf(str, "%g", 1.2e-12)

Result: "1.2e-12"

sprintf() converts the floating point number into a string "1.2e-12" and stores it in the variable str.

Any Number to String

sprintf()with %n format directive

Example:

sprintf(str, "%n", 1.)
sprintf(nil, "%n",1) 

Result:

sprintf() converts the integer or floating-point number (in the [-]ddd.ddd format) number to string.

• get_pname (s_arg): Returns the print name of a symbol as a string
• symbolToString (s_symbolName): Converts a symbol to a string of the same name

Example:

The following functions convert the symbol name x to a string and save it to the variable y:
y=get_pname('x) => "x"
y=symbolToString('x) => "x"

stringToSymbol() converts a string to a symbol

Example: 

The following function converts a string to a symbol:
y=stringToSymbol("test")=> test

List to String

buildString() converts a list to a string

Example:

aList=list("R1" "R2" "R3") => ("R1" "R2" "R3")
buildString(aList ",") => "R1,R2,R3"

String to List

• parseString() breaks a string into a list of substrings with break characters

Example:

parseString("R1 R2 R3\n" )
 =>("R1" "R2" "R3")

parseString() breaks a string into a list of substrings with specified break characters, which are indicated by an optional second argument

Example:

parseString( "Now is the time" ) => ("Now" "is" "the" "time")

The default break character is a space.

parseString( "prepend" "e" ) => ("pr" "p" "nd" )

• axlStringRemoveSpaces strips leading or trailing whitespace from a string

Example:

axlStringRemoveSpaces(" a ")

Result: a

axlStringRemoveSpaces( '(" a " " b "))

Result: '(“a” “b”)
