From: newhand on 19 Nov 2005 14:28 Can someone confirm what is the exact meaning, in Math, of the following two questions? 1. What's the value of the digit 4 in the number 189.064? 2. Round 13.567 to the nearest hundredth. Thanks in advance!

What's the value of the digit 4 in the number 189.064? There is no "exact meaning in Math" to this question. My reasonable guess would be 0.004, but you should ask for clarification from whomever posed the question. > > 2.

My daughter's grade 5 math is reviewing some of these same points, often requesting of them ambiguously as you point out, however, that said, the answers they would want are 4 thousandths (note the d, her 3rd grade teacher did not know that :{ ), and 13.57 (not 13.58). This does seem OT unless there is some underlying C++ aspect to these questions newhand? -- Greg Comeau / Celebrating 20 years of Comeauity!

From: cludeb on 20 Nov 2005 08:17 the value is would be called a four thousandth represented as 4/1000 in math. when rounding up you going to the next decimal number showing only the specified value. example "round 13.567 to the nearest hundredth" would become 13.57 . since your numbers after the decimal point start at a tenth and decrement ...eg.take the fraction value .567 this could be inturperted as 5-tenth, 6-hundedth, 7-thousandth.
