help with fmax

[Unidennn]

Hi, i know its probably the easiest thing ever, but im a noobie in c, and in need of some help with fmax function, i just dont really get it.
im trying to compare 3 floats
heres what im trying
float fmaxf (float int1, float int2, float int3)

im not sure if i can use 3 floats to compare, if not will something like this work
float fmaxf (float int1, float int2)
float fmaxf (float int1, float int3)

the thing i dont understand is what kinda return will be for that fmax function, or should i add something after float function line to get the biggest value out of those 2 or 3 values.. i cant really explain.. i guess i just dont understand how fmax works, we never did it in class but we just took a quick look at math library, so i did the same 3 value comparison with if and else but its very long, i want to try with fmax and fmin to make it shorter
thanks in advance

fmax takes only two variables as input.

So you can only use fmax(a,b)

For three variables a,b,c
use something like

d = fmax(a,b);

e = fmax(c,d)

e will be the max of a,b,c

ohhh....
so to get the largest number out of 2 you just have to make something equal to the fmax function...
thanks for the help .. im gonna give it a try now :)
but another quick question... i need .1f
so if i use ur code

d = fmaxf(float a,float b);

e = fmaxf(float c,float d);

i should use fmaxf or just fmax?

fmaxf for floats.
