Number Type Conversion

Let int i; char c; double d

• Note $c<i<d$ in size i = c is OK since $c<i$ c = i is OK so long as the i fits
• If i doesn’t fit, there are some wack rules you’d have to go through d = i is OK if fits but approximates if it can’t be exact

i = d (truncates towards zero and is OK so long as the number fits)

• It’s better to be explicit than use some random rule that’s hard to remember, so type cast! Also applies to when passing into functions: passing char c into f(int) would implicitly convert the types (cuz char < int)
