real( str );
| Argument | Description |
|---|---|
| str | The string to be converted to a real value. |
Returns: Real
This function can be used to turn a given string into a real
number. When using this function, numbers, minus signs, decimal
points and exponential parts in the string are taken into account,
while other characters (such as letters) will cause an error to be
thrown. If you know, or suspect, that a string may have other
characters then you can use string_digits() to remove all
non-numeric characters, before using this function to turn the
resulting string into a real number.
var t_str;
t_str = string_digits(input_str);
age = real(t_str);
The above code will take the input string, strip it of all characters other than numbers and then set the variable "age" to hold the real number value of the return string.
