Need explain on minecraft vector

[Morteboule]

Hello all,

 

I'm working on my mod but there is something i don't understand in minecraft vector:

 

In method getLook(float par1) in EntityLivingBase

there is f1 = MathHelper.cos(-this.rotationYaw * 0.017453292F - (float)Math.PI);

I don't know what 0.017453292F is?

I know it's not really important to continue my mod but if someone knows what does it mean i would like to know too

 

Thanks!

its a (that decimal) Float value. Google up on Java float values and you probably find the best answer ;3

Yeah i know it's a float value and i've already googled but still don't know what is it
