SCIENTIFIC\_NOTATION _ _ _ _ _ _ _ _ _ _ _ _ declaration

syntax:

<m> and <n> are positive integers. scientific_notation controls the output format of floating point numbers. At the default settings, any number with five or less digits before the decimal point is printed in a fixed-point notation, e.g., 12345.6. Numbers with more than five digits are printed in scientific notation, e.g., 1.234567E+5. Similarly, by default, any number with eleven or more zeros after the decimal point is printed in scientific notation.

When scientific_notation is called with the numerical argument m a number with more than m digits before the decimal point, or m or more zeros after the decimal point, is printed in scientific notation. When scientific_notation is called with a list {<m>,<n>}, a number with more than m digits before the decimal point, or n or more zeros after the decimal point is printed in scientific notation.
