What does 3.199E +01 mean?

Question

What is the exact value of 3.199 E +01 ?
Does it mean $3.199\times10^1$?? I get confused with the notation.

Answer 1

3.199 E +01 is the equivalent of $3.199\times10^1$. The $3.199$ part is the mantissa, E stands for exponential, and $+01$ is the exponent (in base 10).

The number is should like this on some calculators as they cannot display superscript.

Yes, $3.199$E$+01$ is $3.199\times10^1$ in scientific notation or $31.99$.
