[fpc-devel] Getting fpc to work on Solaris (11)
Hi all, I'm trying to set-up a VM with Solaris (x86_64). Problem is that fpc refuses to link applications. It complains that there is a syntax error in the build-in linker scripts. How that's possible, I don't know. When I use -T, so that the default linker scripts are not used, linking goes well, but the application terminates immediately: 'Bad entry point'. That's probably because the link.res link-script is missing too much info to be used without the default linker-scripts. Does this ring a bell to anyone?

The last digits are returned by gdb or the str procedure with precision 15, but won't be displayed in data controls. It doesn't make sense to display more digits than stored in the binary variable. I agree. I just tried to explain what happens behind the scenes. There is no loss, only rounding errors in the conversion from binary to decimal text. There is a small loss. 2^52 = 4503599627370496 which is almost 16 digits. 15 digits can be represented by a 50 bits mantissa. So you're losing 2 bits in precision by truncating to 15 digits. I wrote earlier that the mysql client returned 40734.825668912 when set to 40734.825668912039. That is mysql truncating to 15 characters the string representation of the double for displaying. But when I do a select t_double - 40734.825668 I do get 9.1204e-07. In case of fpc setting the same value select t_double - 40734.825668 returns 9.1200e-07. And that is because fpc converts to a string when updating the value losing the last 2 bits.
