Rounding off 0.3396843234123 to 2 decimal places yields .34, not .33

=0.3396843234, would the [percent] just be 0.33?

Hi Paddy. In addition to proper rounding, the result 0.34 requires a percent sign. Otherwise, people might mistake 0.34 as meaning 34% instead of 0.34%.

We call 0.0034 the 'decimal form' of 0.34%.

The decimal form is what we get when we divide a percentage (like 133) by its whole (39154). Also, people often use the decimal form of a percent in calculations (to avoid having to divide by 100 each time a percent sign is present). We multiply decimal forms by 100% when we desire to express the percent with a percent sign.

Likewise, we interpret % to mean 'divide by 100'. That's how we convert a percent written with % to its decimal form.

0.0034 × 100% = 0.34%

0.34% = 0.34/100 = 0.0034
