| Float and constant comparison : what is wrong ? |

I try to compare a float to a constant (see code below) and I got an error that says that a paren is missing and in fact it is not.
What is wrong ?
Thanks,
D.
| Code: |
float temperature [5];
int8 temperature_haut;
if (temperature [0]>25.0)
(
temperature_haut = (int)10 * temperature [0];
) |
| Code: |
Executing: "C:\Program files\Picc\CCSC.exe" +FH "rtc_ow.c" I+="C:\Program Files\PICC\Devices" +DF +LN +T +A +M +Z +Y=9 +EA
*** Error 58 "rtc_ow.c" Line 799(60,61): Expecting a close paren
*** Error 51 "rtc_ow.c" Line 800(6,7): A numeric expression must appear here
2 Errors, 0 Warnings.
Halting build on first failure as requested.

You have declared an array with 0 elements. That's not allowed.
It gives this error:

Please get book on the C language. |

yeah, I know that.
In fact I summarized the code for the post and I made a mistake in the transcript.
The post is corrected now and the question is still there.

You're using parens and you should be using braces. |
