[GENERAL] problem with float8 input format

[Louis-David Mitterrand]

Hello,

Suddenly I am getting errors with the following function:

    SELECT incr(max_price($1),0.05)

    000810.17:20:41.181  [2246] ERROR:  Bad float8 input format '0.05'
    000810.17:20:41.181  [2246] AbortCurrentTransaction

Where incr() is defined as:

    CREATE FUNCTION "incr" (float8,float8 ) RETURNS float8 AS '
    SELECT CASE WHEN $1 < dpow(10,int8(log($1))+1)/2 
        THEN (dpow(10,int8(log($1)))) * $2 
        ELSE (dpow(10,int8(log($1))+1)/2) * $2 
    END
    ' LANGUAGE 'SQL';

Strangely engough the function call works fine when called from psql but
fails (but not always!) from a C trigger.

Thanks in advance for any help,
