In C++ float value being truncated from double

Question

I\'ve coded using float variables before and never had this problem.

float  a, b, subtotal, stx;
a=15.95;
b=24.95;
subtotal=a+b;
stx=subtotal*.07;

cout <         


        

Answer 1

From standard 2.14.4

The type of a floating literal is double unless explicitly specified by a suffix.
