impl<S: Semantics> Display for IeeeFloat<S>
[src]

Prints this value as a decimal string.

\param precision The maximum number of digits of precision to output. If there are fewer digits available, zero padding will not be used unless the value is integral and small enough to be expressed in precision digits. 0 means to use the natural precision of the number. \param width The maximum number of zeros to consider inserting before falling back to scientific notation. 0 means to always use scientific notation.

\param alternate Indicate whether to remove the trailing zero in fraction part or not. Also setting this parameter to true forces producing of output more similar to default printf behavior. Specifically the lower e is used as exponent delimiter and exponent always contains no less than two digits.

Convert a floating point number to an integer according to the rounding mode. In case of an invalid operation exception, deterministic values are returned, namely zero for NaNs and the minimal or maximal value respectively for underflow or overflow. If the rounded value is in range but the floating point number is not the exact integer, the C standard doesn't require an inexact exception to be raised. IEEE-854 does require it so we do that.
