I have a breakAmt field in my table that is a float datatype. The values need to be in hours. So if employeeA took a break for 1 minute it should be 0.016. If EmployeeB had a 19 minute break it should be 0.316. If EmpC took a 3 minute break I get the value 5.0000000000000003E-2. How can I convert this to leave out the E-2????

The reson I need to maintain a float is because I need to extract these values to a foxpro table that requires a float field. If I use a decimal instead will the export bomb????

Thanks,
Ninel

Your calculation is correct, the E-2 is the exponent, 10 to the minus 2 power.


select	Hours = 3.0000/60.0000,
	Hours2 =convert(numeric(35,20),5.0000000000000003E-2)

Hours              Hours2                                
------------------ ------------------------------------- 
.05000000000       .05000000000000000000



select Hours = convert(float,3)/convert(float,60)

Hours                                                 
----------------------------------------------------- 
5.0000000000000003E-2
