Changed type of TWO43, TWO52 from float to double. * sysdeps/libm-ieee754/e_expf.c (__ieee754_expf): Use __isinff. * sysdeps/libm-ieee754/s_exp2.c (__ieee754_exp2): Use __isinf. Changed type of TWO43 from float to double. * sysdeps/libm-ieee754/s_exp2f.c (__ieee754_exp2f): Fix a typo. Use __isinff.
