float f:
f= b/a * 100;
and then checking with 25 ...

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.
