\在編程中意味着什麼？

我使用以下算法將溫度轉換爲RGB顏色。是否有人知道在第二行意味着什麼？在編程中意味着什麼？

設定溫度=溫度\ 100

這是什麼？

Start with a temperature, in Kelvin, somewhere between 1000 and 40000. (Other values may work, 

Set Temperature = Temperature \ 100 

Calculate Red: 

If Temperature <= 66 Then 
    Red = 255 
Else 
    Red = Temperature - 60 
    Red = 329.698727446 * (Red^-0.1332047592) 
    If Red < 0 Then Red = 0 
    If Red > 255 Then Red = 255 
End If 

Calculate Green: 

If Temperature <= 66 Then 
    Green = Temperature 
    Green = 99.4708025861 * Ln(Green) - 161.1195681661 
    If Green < 0 Then Green = 0 
    If Green > 255 Then Green = 255 
Else 
    Green = Temperature - 60 
    Green = 288.1221695283 * (Green^-0.0755148492) 
    If Green < 0 Then Green = 0 
    If Green > 255 Then Green = 255 
End If 

Calculate Blue: 

If Temperature >= 66 Then 
    Blue = 255 
Else 

    If Temperature <= 19 Then 
     Blue = 0 
    Else 
     Blue = Temperature - 10 
     Blue = 138.5177312231 * Ln(Blue) - 305.0447927307 
     If Blue < 0 Then Blue = 0 
     If Blue > 255 Then Blue = 255 
    End If 

End If

它表示整數除法，給出一個整數結果，與浮點除法不同，它給出了一個浮點結果。 – 2015-07-21 03:31:51

爲什麼rgb標籤在這裏？它與 –
