is_real

This function returns whether a given variable is a real number (single, double or integer) or not. In some cases you want to check and see if a variable holds a real number, and that's when you would use this function. It does not return the real number but rather true or false, so a value of, for example, "fish" would return false, however a value of 200 would return true.

NOTE This function will return false for any enum values as they are stored as int64s. The correct function to check for that data type is is_int64().

Syntax:

is_real(n);

Returns:

Boolean

Example:

if is_real(val)
{
    score += val;
}

The above code checks the variable "val" to see if it is a real number and if it is it then adds it to the score.
