Macro Definition Documentation

◆ BIT_XPL_NBR_SGN_DBL

#define BIT_XPL_NBR_SGN_DBL (52)

Used in quantize code.

Number of explicit bits in significand for doubles. Bits 0-51 of DP significands are explicit. Bit 52 is implicitly 1. Currently redundant with NC_QUANTIZE_MAX_DOUBLE_NSB and with limits.h/climit (DBL_MANT_DIG-1)

Definition at line 44 of file nc4var.c.

◆ BIT_XPL_NBR_SGN_FLT

#define BIT_XPL_NBR_SGN_FLT (23)

Used in quantize code.

Number of explicit bits in significand for floats. Bits 0-22 of SP significands are explicit. Bit 23 is implicitly 1. Currently redundant with NC_QUANTIZE_MAX_FLOAT_NSB and with limits.h/climit (FLT_MANT_DIG-1)
