How do i modify this code so it will show negative temperatures to?

I have been searching the forum but i canīt get it to work or is to dumb to understand..

Code:
DEFINE OSC 20
DEFINE LCD_DREG PORTA       'Set LCD Data port
DEFINE LCD_DBIT 0           'Set starting Data bit (0 or 4) if 4-bit bus
DEFINE LCD_RSREG PORTA      'Set LCD Register Select port
DEFINE LCD_RSBIT 4          'Set LCD Register Select bit
DEFINE LCD_EREG PORTB       'Set LCD Enable port
DEFINE LCD_EBIT 3           'Set LCD Enable bit
DEFINE LCD_BITS 4           'Set LCD bus size (4 or 8 bits)
DEFINE LCD_LINES 2          'Set number of lines on LCD
DEFINE LCD_COMMANDUS 2000   'Set command delay time in us
DEFINE LCD_DATAUS 100        'Set data delay time in us

ADCON1 = 7   ' Set PORTA and PORTE to digital
DQ	Var	PORTB.7  '1820 Datapin

Temperature Var	Word			' Temperature storage
Count_remain Var Byte			' Count remaining
Count_per_c Var	Byte			' Count per degree C
Mainloop: 
    OWOut DQ, 1, [$CC, $44]       ' Start temperature conversion
Waitloop: 
    OWIn DQ, 4, [count_remain]	' Check for still busy converting	        
    If count_remain = 0 Then waitloop

    OWOut DQ, 1, [$CC, $BE]		' Read the temperature
    OWIn DQ, 0, [temperature.LOWBYTE, temperature.HIGHBYTE, Skip 4, count_remain, count_per_c]
    
    temperature = (((temperature >> 1) * 100) - 25) + (((count_per_c - count_remain) * 100) / count_per_c)
    
    Lcdout $fe, 1
    LCDOut $fe, $c0, DEC(Temperature / 100), ".", DEC2 temperature, " C"

    Goto mainloop
