c2bcb21cc6
Previously, we printed all constants in scientific notation with 6 digits of precision. This is not enough to accurately display the smallest value, but increasing the precision would be too much for other values. This patch prints values with fractional bits using only as many digits as needed. 1*2^-15 and 1*2^-16 will be printed in scientific notation while the others are printed without scientific notation. The integer values are printed with a single 0 after the decimal point. Reviewed By: reames Differential Revision: https://reviews.llvm.org/D145645
