7dbff5b9e6 abs: remove support for floats. Use floats.fabs() instead.
this solves: can't use abs() etc in pipe expression because return type depends on argument type
2022-04-14 00:38:31 +02:00
Irmen de Jong
220246278a removed sum(), max(), min(). abs() now always returns uword type.
This greatly simplifies internal handling of builtin functions by always having one fixed return type.

890327b381 the returnvalue of the diskio.load() function family now is just the last load address+1 (like kernal's LOAD routine).
This fixes the inconsistent attempt to calculate a size, just let the caller do this if required.
Added a small helper function in cx16diskio to do this for loads that span multiple banks.
