how many seconds old am i?

By Austin Delauney at 10/06/2010 - 21:00

for some reason line 6 doesnt work.i converted it into a integer but
still i get the error ".
How_old_are_you?.rb:6:in `*': String can't be coerced into Fixnum
(TypeError)
from How_old_are_you?.rb:6
"
the * should work because i tried it. or if someone could tell me how to
do an input as a integer that would be great. but i would see of that
would have to work...

You didn't save the result of .to_i.

That is to say, if you just do:

age.to_i

then that's all the machine does - creates a new int out of 'a'. But it
doesn't hold onto it if you don't tell it to. So you can either assign
it back to itself, somewhere else, or just call .to_i when it's actually
needed:

age = age.to_i

*or*

age_val = age.to_i

*or*

puts 86000*365*age.to_i

As much as I dislike doing someone's homework for them... *shudder* I can't help being anal about calendrical calculations...

There are 86400 seconds in a day, and a fractional number of days in a year (365.242199). You'd be off by more than 2 months for someone my age. Probably not a huge deal for something like this, but you'd be really late to the eclipse...

Are you... 240 years old?

(0.25 days * 240 years = 2 months)

That might explain why Ryan seems to get, shall we say, a bit
crotchety at times. <G>

And I thought *I* was old.

You forgot to account for the lack of 400 seconds (6.666... minutes!) a day. ;)
