use float in no-fpu mips kernel modules?

["renc stone" <renwei@huawei.com>]

hi,
  Any one know how to use float point in mips kernel?
  We use some 2.4.5 kernel, on idt mips 32334, which has no fpu, I think.
  we want to use the float numbers like this:
  float a = 87;
  a * = 1.04;
  Any kernel functions to do this? or how to compile it use soft fpu
support?


     Thanks in advance.
