Fixed comment of float humidity

[NaCl5alt]

Overview

The comment for humidity of type float was written as x1000 even though the value was not multiplied by 1000, so the comment has been corrected to prevent confusion.

Basis

• As shown in the example code below, the value of humidity is not divided by 1000 when FPU is not used.

• Because in the uint32_t calc_humidity method, calc_hum is capped at 100000, but in the float calc_humidity method, calc_hum is capped at 100.0f.
