◆ format()

template<typename UnitTag >
std::string qtty::Quantity< UnitTag >::format ( int  precision = -1,
uint32_t  flags = QTTY_FMT_DEFAULT 
) const
inline

Format this quantity as a string.

Delegates to the Rust qtty-ffi qtty_quantity_format function so that C++ and Rust produce identical output for the same parameters.

Parameters
precisionDigits after the decimal point. Pass a negative value (default) for the shortest exact representation.
flagsNotation selector:
  • QTTY_FMT_DEFAULT (0): decimal (e.g. "1234.57 m")
  • QTTY_FMT_LOWER_EXP (1): scientific lower-case e
  • QTTY_FMT_UPPER_EXP (2): scientific upper-case E
Returns
Formatted string, e.g. "1234.57 m" or "1.23e3 m".
Exceptions
QttyExceptionon formatting failure.
