Datatype storage ---------------- -8 and 16 bit integers are stored as 32bit values. - -32 bit integers are stored in their natural format. - -Floats are stored in their natural format. - -Integers wider than 32 bits are not supported. -Doubles are not supported. +All numeric values are stored in a 32bit wide field. This field contains +a fixed point value with 22 bits assigned to the integer part and 10 bits +assigned to the fractional part. Strings are stored as <pointer,length> pairs, as per css_string. Pointer's width is the native width of a pointer on the platform. Length's width is the native width of a size_t on the platform. CSS dimensions are stored as two 32bit values: <length, units>. -Length is a 32bit integer and unit is as follows: +Length is a 32bit numeric value (as described above) and unit is as follows: bit 8 clear => length unit bits 9-31: MBZ |
