This constant isnt guaranteed to equal to any specific nan bitpattern, and the stability of its representation over rust versions and target platforms isnt guaranteed. Note that ieee 754 doesnt assign any meaning to the sign bit in case of a nan, and as rust doesnt guarantee that the bit pattern of nans are conserved over arithmetic operations, the result of issignpositive on a nan might produce an unexpected result in some cases. 46f32) how does one round a floating point number to a specified number of digits.
