+Subject: [PATCH] BUG: Fix the return type of random_float_fill
+
+The `random_float_fill` function type is declared with return type `double` but
+I think this is a typo. The actual implementation of `random_float_fill` is
+`random_standard_uniform_fill_f` which has return type `void`:
+
+void random_standard_uniform_fill_f(bitgen_t *bitgen_state, npy_intp cnt, float *out)
+
+Also, `random_double_fill` is declared with return type `void`. This fixes the
+return type of `random_float_fill` to match.
