GSAVE behaves differently with int and float arrays

12Me21Created: ~5 years ago

GSAVE saves signed 32 bit values in integer arrays, but UNSIGNED 32 bit when a float array is used.

GCLS #WHITE
DIM FLOAT#[0],INT%[0]
GSAVE 0,0,1,1,INT%,0
GSAVE 0,0,1,1,FLOAT#,0
?INT%[0] '-460552 (#WHITE)
?FLOAT#[0] '4294506744
?HEX$(INT%[0]) 'FFF8F8F8
?HEX$(FLOAT#[0]) 'overflow error

Technically speaking, I don't think GSAVE behaves differently per se, I think it just always writes the unsigned values, which become signed due to overflow with int arrays.
