- convert a wide-character string to a double-precision number

Library

libc.lib

Synopsis

#include <wchar.h>

float wcstof (const wchar_t * restrict src, wchar_t ** restrict endptr);

long double wcstold (const wchar_t * restrict src, wchar_t ** restrict endptr);

double wcstod (const wchar_t * restrict src, wchar_t ** restrict endptr);

Return values

Detailed description

The wcstof, wcstod and wcstold functions are the wide-character versions of the strtof, strtod and strtold functions. Refer to strtod for details.

Examples

#include <wchar.h>
/* Illustrates how to use wcstof API */
int example_wcstof()
{  
  /* src string */
  wchar_t wcs1[21] = L"  1.23abcd";
  wchar_t wcs2[5]=L"abcd";
  wchar_t *eptr;
  float d;
  
 /* convert wide-char string to float */  
  d = wcstof(wcs1, &eptr);
 
  /* compare the result */
  if((d == 1.23F) && !(wcscmp (eptr, wcs2)))
   return 0;
  else
   return 1;
}

#include <wchar.h>
/* Illustrates how to use wcstold API */
int example_wcstold()
{  
  /* src string */
  wchar_t wcs1[21] = L"  1.23abcd";
  wchar_t wcs2[5]=L"abcd";
  wchar_t *eptr;
  double d;
 
  /* convert wide-char string to double */
  d = wcstod(wcs1, &eptr);
 
  /* compare the result */
  if((d == 1.23) && !(wcscmp (eptr, wcs2)))
   return 0;
  else
   return 1;
}
