[Swift-user] floor(), ceil() and round() issues with v0.8.0

[Timothy Stitt (TGAC)]

Thanks Tim.

I don't think those changes made their way into the v0.8.0 user guide that I have with my distribution.  Your suggestion did work though and my old script is now compiling again.

Cheers.

Hi Tim,
  The return type of those functions changed to float in 0.8.0 as part of a bigger effort to standardise the Swift library.  We tried to keep things backwards compatible as much as possible but unfortunately there wasn't a way to do that in this case.

You can get the same effect with toInt(floor(7.8))

Dear Swift/T developers & users,

I've been recompiling a Swift/T script in v0.8.0 (which worked in previous versions) but its failing to compile at the line involving the floor() command. The error I'm seeing is:

stc error:
test.swift:7:6: Cannot assign to t: LVal has type int but RVal has type float

I know that this worked fine in previous versions so I tried to compile with the trivial example below and I get the same error:

import math;
import io;
import sys;

main
{
 int t = floor(7.8);
 trace(t);
}

I substituted floor() for ceil() and round() and got the same error. Is there something wrong with the math library or am I doing something really stupid that I can't see.

Thanks,

Tim.
