SDCC supports (single precision 4 bytes) floating point numbers; the
format is somewhat similar to IEEE, but it is not IEEE; in particular,
denormalized floating -point numbers are not supported. The floating
point support routines are derived from gcc's floatlib.c and consist
of the following routines:
Function | Description |
_fsadd.c | add floating point numbers |
_fssub.c | subtract floating point numbers |
_fsdiv.c | divide floating point numbers |
_fsmul.c | multiply floating point numbers |
_fs2uchar.c | convert floating point to unsigned char |
_fs2schar.c | convert floating point to signed char |
_fs2uint.c | convert floating point to unsigned int |
_fs2sint.c | convert floating point to signed int |
_fs2ulong.c | convert floating point to unsigned long |
_fs2slong.c | convert floating point to signed long |
_uchar2fs.c | convert unsigned char to floating point |
_schar2fs.c | convert signed char to floating point |
_uint2fs.c | convert unsigned int to floating point |
_sint2fs.c | convert signed int to floating point |
_ulong2fs.c | convert unsigned long to floating point |
_slong2fs.c | convert signed long to floating point |
_ulonglong2fs.c | convert unsigned long long to floating point |
_slonglong2fs.c | convert singed long long to floating point |
