f690f58bd4 callfar() now accepts a variable as address, so it can be used to indirect JSR to a subroutine whose address is not fixed. ('goto' already could indirect JMP to a variable address.) 2022-07-14 19:29:59 +02:00

7eea97d741 - floats: remove all floating point builtin functions and move them to the floats module instead 2022-04-22 00:45:54 +02:00

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

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.
