Converting to Integer in PHP

Question

Why in PHP language, the code below prints 7 ?

print (int) ((0.1+0.7) * 10)

While

print (int) ((0.1+0.8) * 10)

prints 9 ?

Because a `int` conversion just strips the decimals and floating point math isn't precise. You could use `round` instead — Philipp, Jul 09 '18 at 09:04

You need to use round() function while converting float values

print (int) round((0.1+0.7) * 10);

You don't *need* to. It depends on what the goal is. – deceze Jul 09 '18 at 09:07
