Your email address will not be published. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, What outputs do you get for the following? For our purpose, we need not mention any argument as, by default, it takes the parameter to be 0, hence returning an integer value. If mod is present and exp is negative, base must be relatively prime to mod. Also in single topic you cover all concepts, later on you have different discussion on those topics. A float value is only accurate upto 15 decimal places. Number.toFixed() rounds of the decimal value of float less than .5 to the lower integer value. For example, using x = np.array(1.344566), x.astype('str') yields '1'! Following are a few conversions with Math.ceil(). We sometimes encounter an exception that a variable is of NoneType. Lets look at some examples of using the above syntax to convert an integer value to a float. parseInt(), Math.trunc() and the bitwise operators (OR by 0, Double NOT, right shift by 0) give the exact whole number as if they tear the float value at the decimal point and return just the whole number part out of it. For int operands base and exp, if mod is present, mod must also be of integer type and mod must be nonzero. Lets try out adding 1.1 and 2.2 in the shell, and lets compare it with 3.3. This method can be considered similar to the bitwise operators discussed earlier.
