Classes and Methods

MSMath

A class that contains mathematical utility functions.

• clamp: Constrain (or clamp) a numeric value between two bounds.

  MSMath::clamp(mixed $value, mixed $min, mixed $max): int|float

• lerp: Linearly interpolate between two values.

  MSMath::lerp(float $start, float $end, float $t): float

• inverseLerp: Calculate the inverse linear interpolation of a value between two bounds.

  MSMath::inverseLerp(float $start, float $end, float $value): float

• remapRange: Remap a value from one range to another.

  MSMath::remapRange(float $value, float $oldMin, float $oldMax, float $newMin, float $newMax): float

• mean: Calculate the mean of an array of numbers.

  MSMath::mean(array $values): float

MSGeoHash

A class that contains geohash utility functions.

• encode: Encode a latitude and longitude into a geohash string.

  MSGeoHash::encode(float $latitude, float $longitude, int $precision = 12): string

• decode: Decode a geohash string into a latitude and longitude.

  MSGeoHash::decode(string $hash): array

• distance: Calculate the distance between two geohash strings. Returns the distance in kilometers.

  MSGeoHash::distance(string $hash1, string $hash2): float

• neighbor: Calculate the neighbor of a geohash string in a given direction (N, S, E, W, NW...).

  MSGeoHash::neighbor(string $hash, string $direction): string

• neighbors: Calculate the neighbors of a geohash string in all directions (N, S, E, W, NW...).

  MSGeoHash::neighbors(string $hash): array

MSMisc

A class that contains miscellaneous functionality.

• toExcelColumn: Convert a number to an Excel column name.

  MSMisc::toExcelColumn(int $number): string

• fromExcelColumn: Convert an Excel column name to a number.

  MSMisc::fromExcelColumn(string $column): int
