I would like to know why are they adding 48.
// Convert temp_fraction to characters text[4] = temp_fraction/1000 + 48; // Extract thousands digit text[5] = (temp_fraction/100)%10 + 48; // Extract hundreds digit text[6] = (temp_fraction/10)%10 + 48; // Extract tens digit text[7] = temp_fraction%10 + 48; // Extract ones digit
Thanks for your help 🙂
It is to convert each extracted digit to corresponding character.
‘0’ => 0 + 48
‘1’ => 1 + 48
‘2’ => 2 + 48
etc.Please refer ASCII Table for more reference.
