----------------------------------- syntax_error Wed Sep 26, 2007 12:30 pm long into a float ----------------------------------- a genral question as far as I know a long is 8 bits and a float is 4 bits then why in java you can automaticly cast a long into a float? thx in advance Syntax_Error ----------------------------------- StealthArcher Wed Sep 26, 2007 12:34 pm Re: long into a float ----------------------------------- I think you have those backwards..... longs are 4 bytes if i remember correctly ----------------------------------- HeavenAgain Wed Sep 26, 2007 2:45 pm RE:long into a float ----------------------------------- data type size (in bits) range byte 8 -2^7 to 2^7 - 1 short 16 -2^15 to 2^15 - 1 int 32 -2^31 to 2^31 - 1 long 64 -2^63 to 2^63 - 1 type in bytes float 32 double 64 a long is 64 bits a byte IS 8 bits and a float is 32 BYTES more info is linked here ----------------------------------- wtd Wed Sep 26, 2007 5:14 pm Re: RE:long into a float ----------------------------------- and a float is 32 BYTES Ummmm... ----------------------------------- Zampano Wed Sep 26, 2007 6:55 pm Re: long into a float ----------------------------------- How much memory would I need to take a byte out of a sundae double banana ice cream float? *My own lameness is astounding.* ----------------------------------- McKenzie Wed Sep 26, 2007 7:30 pm Re: long into a float ----------------------------------- I thought the automatic cast was to double? That aside, the reason for the automatic conversion is that long is a long integer, as soon as you have any fractional component to a number long can't hold it (e.g. 3.5) ----------------------------------- Nick Wed Sep 26, 2007 8:19 pm RE:long into a float ----------------------------------- zampano ur bytes are so small it takes 4 to equal a nybble (AHAHAHAHA) [btw 4 bytes = a nybble] ----------------------------------- rizzix Wed Sep 26, 2007 9:46 pm RE:long into a float ----------------------------------- Wow a lot of you are misusing the word byte for bit. 1 byte = 8 bits 1 nibble = 4 bits Int's/floats are 32-bit or 4-byte. Long/doubles are 64-bit or 8-bytes. ----------------------------------- rdrake Wed Sep 26, 2007 10:00 pm Re: RE:long into a float ----------------------------------- Wow a lot of you are misusing the word byte for bit. 1 byte = 8 bits 1 nibble = 4 bits Int's/floats are 32-bit or 4-byte.
