Description: Procedure Description: BCD floating-point numbers into a compression code, stored in the array in the first 1-bit byte is 7:0, one negative. Bit 6:0 (bit 5 0 on behalf of the decimal point in front of the median), 1 (bit 5 0 on behalf of the digit after the decimal point 0) 2 4 bytes for the compressed BCD code, valid for 7-bit, three semi-byte, the last half-byte user to opt-out procedure, please occupied resources PSW, A, B, DPTR , R0 R7, SP depth of 6, RAM 5 months keil release data compatibility, subprogram call KEIL the FPMUL. Procedures Author :************* Chen expedition************** Objective: To pursue the implementation of faster speed, with the smallest code Published: 2003 05 08 the preparation of background: proficient in the compilation, research C51 half a month.
