In case "appropriate format string" isn't obvious, note that it depends on what output you're trying to produce. If you want floating point numbers to be rounded to the nearest integer, use %.0f. If you want floating point numbers to be truncated to the largest integer that is less than or equal to the floating point number, use %d.

Description
The and routines return the largest integer which is not greater than x for double and float data types, respectively.
The and routines return the smallest integer which is not less than x for double and float data types, respectively.
The and routines return the integer (represented as a floating-point number) of x with the fractional bits truncated for double and float
data types respectively.
The routine returns the absolute value |x|.
The routine returns the floating point remainder of the division of x by y: zero if y is zero or if x/y would overflow; otherwise the num-
ber f with the same sign as x, such that x = iy + f for some integer i, and |f| < |y|.
The routine returns the integer (represented as a double precision number) nearest x in the direction of the prevailing rounding mode.
In the default rounding mode, to nearest, is the integer nearest x with the additional stipulation that if |rint(x)-x|=1/2 then is even.
Other rounding modes can make act like or or round towards zero.
Another way to obtain an integer near x is to declare (in C)
double x; int k; k = x;
The C compiler rounds x towards 0 to get the integer k. Also note that, if x is larger than k can accommodate, the value of k and the
presence or absence of an integer overflow are hard to predict.
The routine is in libc.a rather than libm.a.
