StringToNum- Converts the string into a numerical value

Function that converts the string containing the textual representation of the number in the relative numerical value.

- StringToNum(S[,D]): num

Parameters:

- (string) S: A string containing the textual representation of the number to be converted;

- (num) D: Default value in case of error (optional).

Description:

Use the StringToNum function to convert the text representation of a number to its numerical value. The result can be an integer or floating point number, depending on what the string contains. If the S string contains an invalid number, an error is generated. The optional parameter D is the default value that is returned if the number is invalid.

Examples:

// Stores the value of the string in the variable N

N = StringToNum('1234')

MsgBox(N)

// An error is generated because the string does not contain a valid number

N = StringToNum('123abc')

// The number -1 is returned because the string does not contain a valid number

N = StringToNum('123abc',-1)
