Actually, with 9 numbers it's fine, but with 10 it doesn't work :o
For some odd reason, it could work with a number of decimal places higher than 10 ;l
I know this because I have this test map made by D4RK_G4ND4LF in which he defines Pi to God knows how many digits and it works perfectly.
I don't know if this is only for timers though.
I'll test later with 8 - 20 digits and see what happens.
