How to calculate
Split a number into a coefficient and a power of ten using a supplied exponent.
Coefficient = value/10^exponent; Reconstructed value = value/10^exponent*10^exponent
Worked example
Number: 123000; Power of ten: 5.
Coefficient: 1.23 ; Reconstructed value: 123,000 .
Assumptions and limits
Choose the exponent so the coefficient magnitude is at least one and below ten for normalized notation.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
