Dividing by half in ruby to create an effective calculator -


for past while i've been working on calculator, have run problems when needing divide half. i'll add offending bit of code along loop keep open below.

on = true while on == true     half = 1.0 / 2.0     puts ("function in testing mode, not expect function properly")     puts ("area of triangle")     print("what legnth of base? ").to_i     base = gets.chomp("base")     print("\nwhat height? ")     height = gets.chomp("height").to_i     preareat = base * height     areat = preareat * half     puts("the area of triangle #{areat}") end

so essentially, how on earth program display answer, rather outputting nothing answer?

edit:as turn out code above improperly done. i've spent 2 weeks asking myself why wouldn't work find had .to_i after print statement rather input.

your to_i call switched around here.

print("what legnth of base? ").to_i base = gets.chomp("base")

should other way 'round.

print("what length of base? ") base = gets.chomp("base").to_i

further, chomp attempt remove occurrences of base or height string. sure you're intention remove occurrences; if want remove whitespace, you'll have take different approach.
