extractDouble()

static bool extractDouble ( IteratorT &  begin, const IteratorT &  end, double &  target  )

inlinestatic

Reads a double from an iterator position. The begin iterator is modified (advanced) if parsing was successful. The target only contains a valid result if the functions returns true (i.e. parsing succeeded). Whitespaces before and after the double are NOT consumed!

Referenced by OpenMS::StringUtils::extractDouble().

toDouble()

static double toDouble ( const String &  s )

inlinestatic

convert String (leading and trailing whitespace allowed) to double

s Input string which represents a double, e.g. " 12.3 "

Returns

A double representation of s

Exceptions

Exception::ConversionError

if the string is not completely explained by the double (whitespaces are allowed)

toFloat()

static float toFloat ( const String &  this_s )

inlinestatic

Referenced by OpenMS::StringUtils::toFloat().

toInt32()

static Int toInt32 ( const String &  this_s )

inlinestatic

toInt64()
