Question

what is the scientific notation for the float number 0.0000001234

Answer 1

Scientific notation :

This is a number which has one digit to the left of the decimal point.

We therefore get one digit to the left of the decimal point and multiply it with 10 raised to the number of decimal places.

The ten could be raised to a negative power or a positive power.

We raise ten to a negative power if the number is less than one and raise it to positive if n is more than one.

Therefore the above number in scientific form is :

= 1.234 × 10⁻⁷
