FmtFloatT< T > Struct Template Reference

#include <evo/impl/str.h>

Detailed Description

template<class T>
struct evo::FmtFloatT< T >

Explicitly format a floating pointer number.

• Used with operator<<() on String, Stream, and StreamOut
  • See String Formatting and Stream Formatting
• Don't use FmtFloatT directly, use one of the aliases:
  • FmtFloat, FmtFloatD, FmtFloatL

Example

Example using FmtFloat

#include <evo/string.h>
using namespace evo;

int main() {
    // Format string as: 01.230,4.56
    String str;
    str << FmtFloat(1.23, 3, 6) << ',' << 4.56;

    return 0;
}

Constructor & Destructor Documentation

FmtFloatT() [1/2]

FmtFloatT ( T  num, int  precision = fpCURRENT, int  width = -1, char  ch = '0', char  ch_sp = ' '  )

inline

Constructor for POD number type with all attributes.

Parameters

num	Number to format
precision	Precision to use (number of digits after decimal), fPREC_AUTO for automatic (default: fPREC_AUTO)
width	Width to pad to, -1 for unspecified (default: 0)
ch	Padding character to use, 0 for unspecified (default: '0')
ch_sp	Padding character to use with special value (inf or nan), 0 for unspecified (default: ' ')

FmtFloatT() [2/2]

FmtFloatT ( const FloatClass &  num, int  precision = fpCURRENT, int  width = -1, char  ch = '0', char  ch_sp = ' '  )

inline

Constructor for class number type (Float, etc) with all attributes.

Parameters

num	Number to format
precision	Precision to use (number of digits after decimal), fPREC_AUTO for automatic (default: fPREC_AUTO)
width	Width to pad to, -1 for unspecified (default: 0)
ch	Padding character to use, 0 for unspecified (default: '0')
ch_sp	Padding character to use with special value (inf or nan), 0 for unspecified (default: ' ')
