A read some posts here and google and don´t find a substancial answer. Supose I have a largest number and I have to assing to a variable. The problem raise when I have a GUI where the user will enter the number. How I can´t know what the value the user will put in a field (let´s think in a UItextField), when I get the number and then assign this to a variable, if the number is more large them max with the type of var I will have the overflow and a
inconsistent number. Other situation is whem I have to some values and I have to sum all. If the total sum is more large of the type the variable I will get the overflow again.
How can a compare the value inputed by user whith the max of the type of variable? I know have a constats for the mim and max, but if someone have a example code will help.
Limit the number of digits the user can enter, use an integer type that can accommodate all the user’s digits to check for overflow (floating point if necessary).
