I don't see why how many people downvote my question if 4 people have upvoted the answer.. You don't see how a question can be considered bad and an answer to the same question good? How about a hypothetical question that is so vague as to make it difficult to answer, shows no research, and poor grammar?

Such a question could still receive a clear, explanatory, authoritative answer and still be a bad question. Add a comment. Active Oldest Votes. If the input is 0, the result is all 0 bits. If the input is negative, set the sign bit to 1, and complement the input. Find the highest bit set. The syntax is as follows:. Please keep in mind that the LEN gth parameter is for the destination tag or array of tags. In this example, a float value of ' Specifically, MCM. ReadData[0] will contain the value and MCM.

If your program is printing 0. See here for more details on these output forms. I wrote this converter from scratch — it does not rely on native conversion functions like strtod or strtof or printf. Following are a few examples that showcase the usage and how it converts a float to a whole number. The case of negative float numbers like Math. Recollect that the higher the numeric value of a negative number, the lesser is its actual value.

Unlike the Math. If the value after the decimal is 5 or greater, then the number is rounded off to the next higher integer. Else, if the value after the decimal is lesser than 5 , it is rounded to the lower integer. Hence, based on the value post the decimal point, Math. Following are a few examples with Math. Instead of rounding off to the next lower integer as in Math. Following are a few conversions with Math. As the name hints, the Math. This method can be considered similar to the bitwise operators discussed earlier.

Here, there is no rounding off to the nearest integers. Instead, it returns the whole number part of the float value as it is. Following are a few use cases with Math. There are various ways to get the whole number part out of a float value.
