Function Documentation

void V_float_accuracy

(

int

n

)

Set number of decimal places.

V_float_accuracy() defines the number of decimal places in which floats and doubles are displayed or accepted. Num is an integer value defining the number of decimal places to be used. This routine affects subsequent calls to V_const() and V_ques(). Various inputs or displayed constants can be represented with different numbers of decimal places within the same screen display by making different calls to V_float_accuracy() before calls to V_ques() or V_const(). V_clear() resets the number of decimal places to the default (which is unlimited).

Parameters
