Detailed Description

template<typename Scalar, const bool isFloatingPoint = ! Teuchos::ScalarTraits<Scalar>::isOrdinal>
class Teuchos::SetScientific< Scalar, isFloatingPoint >

Temporarily make an output stream use scientific notation with sufficient precision.

On construction, apply the necessary flags to the given output stream so that floating-point numbers are written in scientific notation with precision (dependent on the Scalar type) sufficient to ensure that they can be read in with the same value. On destruction, restore the original (pre-construction) flags to the output stream.

This makes SetScientific good for scope-protected alteration of the output stream's flags; no matter how the scope exits (normally or by a thrown exception), the original flags will be restored. Hence, "temporarily" (or even "politely"): we restore the original flags on scope exit.

Template Parameters

Scalar

A floating-point type, either real or complex, for which Teuchos::ScalarTraits<Scalar> has a specialization.
