To what value would a dew point temperature of -11.6 be rounded for reporting?

The dew point temperature of -11.6 is rounded according to the standard practices used in weather reporting, which typically involve rounding to the nearest whole number. In this case, when rounding -11.6, the decimal value is examined. Since the digit following the decimal point is 6, it is significant enough to round the whole number down to -11.

Given the options, the correct rounded value of -11.6 would therefore be reported as -12. The rounding rule applied here indicates that anything .5 and above rounds up, while anything below .5 rounds down. As -11.6 is closer to -12 than it is to -11, it becomes the correct reporting value.

Understanding this rounding process is essential for accurate weather reporting and ensures consistency in how meteorological data is communicated.
