Lines Matching defs:mantissa

93 // formula: floor((mantissa * 2^exponent)/10^i) % 10^9.
101 // when multiplying by the mantissa we reverse this by dividing by 2^c, like so:
102 // floor((mantissa * table[exponent][i])/(2^c)) % 10^9.
135   // conversion to get an explicit mantissa of 0x13441350fbd738 and an exponent
136   // of -2 (which becomes -54 when we shift the mantissa to be a non-fractional
137   // number). Next I shifted the mantissa right 12 bits to create more space for
169 // index (which is ceil(exponent/16)) and mantissa width could need.
