int s = 1e9;
What is type of 1e9 and how precise is it? (Is it exactly equal to 1000000000?)
Printing type of a value/variable to stdout would be useful if it’s possible.

1e9is adoublethat has an exact representation in the IEEE floating point representation. The C++ standard doesn’t mandate IEEE floating point.sis anint, so thedoublevalue will be automatically converted to anint. How this takes place is to some extent up to the implementation. On most machines nowadays, this conversion meansswill be given an initial value of 1000000000.
