Function NewFromFloat32

decimal.go:316–323

NewFromFloat32 converts a float32 to Decimal. The converted number will contain the number of significant digits that can be represented in a float with reliable roundtrip. This is typically 6-8 digits depending on the input. See https://www.exploringbinary.com/decimal-precision-of-binary-floating-
