Description

Syntax

strfloat(string[]);

Parameters

Variable	Input

Variable

Input

string

A string containing a ﬂoating point number in characters. This may be either a packed or unpacked string.

The string may specify a fractional part, for example “123.45”.

Returns

The value in the string, or zero if the string did not start with a valid number.

Function call example

Example of converting string to float

new data1[7] = ''125.89'';
new Float: strToFl;
   
main(){
 strToFl = strfloat(data1);
  while(1){
    Delay(100);                                     
  }
}

Notes and Warnings

Use unpacked string by writing two times single comma (''example'') instead of writing single double comma ("example").

When using unpacked string always leave one more array element:

^{new data1[7] = ''125.89'';}

Here we see that to store whole string we'd need only 6 array elements (since 125.89 is 6 elements), but we have to add one extra array element to store final zero, that's why data1 array size is 7 instead of 6.
