numeric :: rounding

Definition:

FRound(float x, int decimals)

Description:

Returns x rounded to decimals accuracy, taking care not to overflow during the intermediate calculations. The result is a float number.

Note that when using negative decimals it is possible to zero the result if x < 0.5*Pow(10,-decimals).

Examples:

f1 = 2.345613

f2 = FRound(f1, 2) # f2 == 2.34

f3 = 2132.345

f4 = FRound(f3, -2) # f4 == 2100
