Synopsis
Header: fxcg/misc.h
Syscall index: 0x0160
Function signature: int BCDtoInternal(struct BCDinternal* target, struct BCDvalue* source)
Converts a BCD-coded digit to its special internal representation. Helps saving code when converting a BCD value to a double.
Parameters
- target - pointer to a struct that will hold the conversion result. The struct is as follows:
struct BCDinternal { int exponent; int sign; int unknown; char mantissa[15]; }
- source - pointer to BCD value to convert. The struct containing it is as follows:
typedef struct{ unsigned char hnibble:4; unsigned char lnibble:4; } TBCDbyte; typedef struct{ unsigned short exponent:12; unsigned short mantissa0:4; TBCDbyte mantissa[7]; char flags; short info; } TBCDvalue;
Returns
0 on success, -1 on error.
