you need to specify enough "digits" (you also forget an 'f' in your format).

try
print,string(-4.35660,format='(f5.2)')
-4.36

Note that there are 5 characters in the printout, including the negative
sign and the decimal.

Cheers,
bob

PS the **** indicates that the number does not fit into the defined format
statement.
The answer is usually to make the format bigger.
