strval()

Description

Convert from text (string) to numbers.

Syntax

strval(string[], index);

Parameters

Variable	Input

Variable	Input
`string[]`	The string containing a number in characters. This may be either a packed or unpacked string
`index`	The position in the string where to start looking for a number. This parameter allows to skip an initial part of a string, and extract numbers from the middle of a string

NOTE: if string starts with 0x00, strval(string, index) will return 0 even when using index to skip those bytes. Workaround is strval(string[index]).

Returns

The value in the string, or zero if the string did not start with a valid number (starting at index).

Function call example

Example of converting string to value

new array1[30]=''4, 8, 15, 14, 23, 42''; 
new val;
  
main(){  
  val = strval(array1, 3);  // result of val = 8;
  while(1){
    Delay(100);                                  
  }
}
