How to get absolute value from double - c-language

Question

I want the absolute-value from a negative double - and I thought the abs-function was as easy to use as in java - but NOT   It seems that the abs-function returns an int because I have the value 3 8951 and the output is 3 000000  double d1   abs -3 8951   printf  d1      lf   d1     How can I fix this problem  That is - I want the absolute value of a double
