[LTP] Bug for "math"

[Wang B. T. <bt...@it...>]

Dear colleagues:
     When I run "float_bessel","float_exp_log", "float_power" and
"float_trigo" on an embedded board with 40M memory, the results
display they are flaure, but I don't know how to solve this problem
and need your help!
     Thanks for your time and patience!
