Detailed Description

A number manipulation class.

This is used to extract, convert, and manage simple numbers that are represented in C ascii strings in a very quick and optimal way. This class modifies the string representation each time the value is changed. No math expressions or explicit comparison operators are supported for the Numbers class because these are best done by casting to long first.

long ucommon::Number::get ( ) const

Get value of string buffer as a long integer.

Returns
long integer value of string buffer.

◆ operator char *()

ucommon::Number::operator char * ( ) const
inline

Cast object as a string to retrieve buffer.

Returns
string buffer of value.

Parameters
numberto assign to assign.
Returns
new value of number object assigned.

◆ operator=() [2/2]

long ucommon::Number::operator= ( long value)
