Question

what are the return type of max 2 min 3 round 4 exp 5 log 6 pow ?​

Answer 1

Answer:

The Math.pow() function returns the base to the exponent power, that is, baseexponent, the base and the exponent are in decimal numeral system.

Because pow() is a static method of Math, you always use it as Math.pow(), rather than as a method of a Math object you created (Math has no constructor). If the base is negative and the exponent is not an integer, the result is NaN.

Examples

Using Math.pow()

// simple

Math.pow(7, 2); // 49

Math.pow(7, 3); // 343

Math.pow(2, 10); // 1024

// fractional exponents

Math.pow(4, 0.5); // 2 (square root of 4)

Math.pow(8, 1/3); // 2 (cube root of 8)

Math.pow(2, 0.5); // 1.4142135623730951 (square root of 2)

Math.pow(2, 1/3); // 1.2599210498948732 (cube root of 2)

// signed exponents

Math.pow(7, -2); // 0.02040816326530612 (1/49)

Math.pow(8, -1/3); // 0.5

// signed bases

Math.pow(-7, 2); // 49 (squares are positive)

Math.pow(-7, 3); // -343 (cubes can be negative)

Math.pow(-7, 0.5); // NaN (negative numbers don't have a real square root)

// due to "even" and "odd" roots laying close to each other,

// and limits in the floating number precision,

// negative bases with fractional exponents always return NaN

Math.pow(-7, 1/3); // NaN
