Parameter | Type | Description |
---|---|---|
x | % | a float |
n | MachineInteger | a precision |
Description
precision(x) returns the precision acutally used for , while setPrecision!(x, n) sets the precision for to be at least bits.
Remarks
Those functions are wrapper to the mpf_get_prec and mpf_set_prec GMP functions, so setPrecision! can involve a call to realloc.
