console.log(DeltaPrueba); // 1
var menor = Math.min(DeltaPrueba);
console.log(menor); //1
}
Service
CalculateDeltas(){
/* do some math to calculate then save in array Deltas*/
Deltas = [DeltaT1,DeltaT2,DeltaT3,DeltaT4,DeltaT1CR,DeltaT2CR,DeltaT3CR,DeltaT4CR] ;
}
getDeltasRx1(){
return Deltas;
}
Console log number 1 show the array with all de data like this:
["18.20", "0.00", "425.97", "316.87", "667.80", "422.34", "425.99", "316.89"]

You need to do the following
var array = ["18.20", "0.00", "425.97", "316.87", "667.80", "422.34", "425.99", "316.89"]; var min = Math.min.apply(Math, array); console.log(min);
To convert the whole array from strings to numbers you can do
array.map(Number)
but this won't have any impact on getting the min value, as behind the scenes javascript will convert each of these strings to numbers.
