Largest float value KDB can handle

Whats the largest decimal value KDB can handle. Im looking to deal with numbers that have over 17 decimal places

Hi ekallivrousis,

The largest decimal value would be the float type as per Data types

q)(2 xexp 1023)*1+1-2 xexp -52 1.7976931348623157e+308

See here for more Double-precision floating-point format 

Also note that the q console can only display float values to 17 significant figures, e.g.

q)\P 7i q)1.123456789 1.123457 q)\P 0 /this is eqiuvalent to \P 17 q)\P 0i q)0.11111111111111112 0.11111111111111112 q)1.11111111111111112 1.1111111111111112
