If no errors occur, the base-e exponential of arg (earg ) is returned. If a range error due to overflow occurs, +HUGE_VAL, +HUGE_VALF, or +HUGE_VALLis returned. If a range error occurs due to underflow, the correct result (after rounding) is returned. See more Errors are reported as specified in math_errhandling. If the implementation supports IEEE floating-point arithmetic (IEC 60559), 1. If the … See more For IEEE-compatible type double, overflow is guaranteed if 709.8 < arg, and underflow is guaranteed if arg < -708.4. See more
WebNov 30, 2024 · 1 Answer. float prop::storefloat (float inp) { std::cin >> inp; return 1; } This is pass-by-value, as your book should tell you. You can change the local inp, but it does not affect the caller. The return value 1 is pointless here, while return values are the logical way to return a value to the caller.
