  Further information
 
 
  This function performs the same conversion as
 printf, in particular it handles special values
 nan and
 inf and reports
 0 if the value to convert is smaller than the current zero tolerance (Mosel parameter
 zerotol). If the provided
 realfmt is
 NULL, the format defined in the current context is used (Mosel parameter
 realfmt).
